My GP wanted to put me on gabapentin for the rest of my life. Six months later, my nerves had stopped dying and the feeling in my feet was coming back. I never even filled the prescription. I've been a nurse for 32 years. I've watched hundreds of patients start nerve pain medication. Gabapentin, usually. The "gold standard," doctors call it. I've also watched what happens to them over the years that follow. The brain fog that never lifts. That cloudy, disconnected feeling that makes them seem like they're not fully present. Families tell me, "It's like talking to someone underwater." The dizziness that leads to falls. I've seen patients with black eyes, split foreheads, broken hips, all because their balance gave out and their numb legs couldn't catch them. The weight gain. One patient gained nearly two stone in a single year. "I don't even eat that much," she told me. "It just keeps coming." Another lost the coordination in her hands and couldn't tell me why. The exhaustion. Patients who used to be sharp, engaged, full of life, now asleep in the chair by 7 in the evening, unable to follow a conversation. And the dependence. Year after year, I've watched doses climb. 300mg becomes 600mg becomes 900mg becomes 1200mg. And if they try to stop? The withdrawal is brutal. Anxiety, insomnia, tremors. Some say it's worse than the original pain. But here's what haunts me most. The nerve damage keeps progressing. The medication masks the pain, but it doesn't stop the destruction. I've watched numbness spread from toes to feet to ankles to calves, while patients thought the gabapentin was "working." So when my own feet started tingling, that electrical buzzing that wouldn't stop, and my GP mentioned starting gabapentin, I smiled politely and said I'd think about it. But I already knew I wasn't going to take it. I'd seen too much. I wasn't going down that road. Now, I should tell you where mine came from, because it matters. I'm a Type 2 diabetic. Thirteen years. Well controlled, on metformin, HbA1c exactly where my GP wanted it. He always told me my numbers were good. And the whole time my numbers were "good," the feeling was quietly leaving my feet. Compression socks. Capsaicin creams. Those expensive massage devices. I have a drawer full of this stuff. The creams burn for about an hour and then wear off. The socks feel okay during the day but they don't help at night when it actually matters. And night was the worst. 2am, feet burning like I was walking barefoot on broken glass, hanging them off the side of the bed hoping the air would cool them down. The massage thing felt nice for about twenty minutes. Then the pain came right back. So I did what I'd tell any patient to do, except I actually had the training to read the real thing. I didn't go to the wellness blogs. I went to the places I trusted from three decades on the wards. PubMed. The Cochrane reviews. The diabetic neuropathy trials themselves. And everything kept pointing to the same nutrient. B12. Specifically the active form, methylcobalamin. There were randomised trials on it, real ones, showing it could actually improve nerve conduction in diabetics, not just mask the pain the way gabapentin does. This was the science. This was my way out. My alternative to the medication I refused to take. I ordered high quality B vitamins, the active forms, methylcobalamin and methylfolate. Took them every single day for eight weeks. My tingling? Still there. Maybe slightly less intense. Hard to tell. My GP's office rang. "Mrs Blake, your symptoms are still progressing. The doctor wants to discuss starting medication at your next appointment." I told them I needed more time. They agreed to push it back a few months. I doubled down. Took the tablets religiously. Another ten weeks. The tingling spread to my ankles. I was running out of options. And I was running out of time. My next appointment was in six weeks. If my symptoms weren't improving, I knew what was coming. The prescription pad. The chemist. The slow cognitive decline I'd watched happen to patient after patient. I almost gave up. Almost concluded that supplements just didn't work for me. That maybe I was foolish to think I could avoid medication. That maybe I should just accept it. I'd spent hundreds of pounds on bottles by then, and I had nothing to show for it. But after 32 years as a nurse, I know something about treatments that don't work. Usually, it's not that the treatment is wrong. It's that something about the delivery is wrong. So instead of surrendering to gabapentin, I started asking a different question. Not "does B12 work?", the trials already answered that. But "why isn't any of it reaching my nerves?" I went back into the pharmacology. The absorption studies. The papers on B12 status in patients on long term metformin, and there were a lot of them, more than I expected. And what I read made me furious, because I'd been a nurse for 32 years and nobody had ever spelled it out to me this plainly. Three things were happening at once, and every one of them was documented. First, the form. Almost every B12 on the shelf is cyanocobalamin, the cheap, inactive form. Your body has to convert it before a nerve can use it, and that conversion weakens with age, and weakens further on metformin. I'd at least got that part right, I'd bought methylcobalamin. But I'd still swallowed it. Second, the absorption. The studies were blunt. After fifty, the stomach stops making enough intrinsic factor, the one protein that carries B12 out of the gut and into the blood. So a swallowed tablet, whatever the number on the label, mostly passes straight through you. By the time any active B12 reaches the peripheral nerves in your feet, the farthest point in your body from your stomach, only a fraction of what was on the label is left. Third, the drain nobody had told me about. Paper after paper, going back decades, showing that metformin itself depletes B12. It's in the drug's own prescribing information. I had prescribed metformin to patients for years and never once connected it to the numbness creeping up their feet. My nerves weren't failing because I wasn't taking B12. They were failing because a swallowed tablet couldn't get it to them, and my metformin was draining what little did. It wasn't a supplement problem. It was a delivery problem. And here's the part that made me laugh out loud, the bitter kind of laugh. I'm a nurse. I have watched medicines given under the tongue for 32 years. We do it precisely because that tissue carries a drug straight into the bloodstream and skips the stomach entirely. When a patient can't absorb something through the gut, you go under the tongue. I knew this. I just never once thought to apply it to my own feet. But here's what really made my blood boil. Nobody talks about this. Every nerve supplement on the shelf lists methylcobalamin on the label. Not one of them tells you how little of it actually survives the trip to your feet. They just print "nerve support" and let you blame yourself when the numbness keeps creeping up. So you're buying supplements. Taking them faithfully. Watching your numbness spread anyway. Watching your appointment get closer. Feeling the medication becoming inevitable. Blaming yourself. Concluding that natural solutions "don't work." When really, the nutrient was right. It just never arrived. Not one product in your cupboard was built to actually get it there. I'd spent five months swallowing the right nutrient in a form my body broke down before it could help, while my metformin drained the rest. Five months of my nerves starving for B12 that never reached them. Five months closer to the prescription I was desperate to avoid. But I also felt something I hadn't felt in weeks. Hope. Because if the problem wasn't the nutrient, if the problem was that a swallowed tablet can't carry it to the nerve, then maybe there was a way to deliver it that actually worked. Maybe I wasn't out of options after all. So I started searching the absorption research for the other way in. How do you get B12 into the bloodstream without sending it through a stomach that's stopped absorbing it? The answer was sitting in the literature, and it was the one I'd been using on patients my whole career. Sublingual. Under the tongue. There are comparison studies, sublingual methylcobalamin against injections, showing the under-the-tongue route reaching blood levels the swallowed tablets never touched, because it absorbs through the tissue in the mouth straight into the bloodstream and skips the gut entirely. We use that route in hospitals precisely because it bypasses a digestive system that can't be trusted to absorb. I'd given medicines that way for 32 years. I'd just never thought to apply it to my own feet. That was the whole answer. Not a stronger tablet. A different way in. So I knew exactly what I was looking for now, and it was a short list. Active methylcobalamin, not cyanocobalamin. A real dose, the studies used around 5,000 micrograms, not the few hundred hidden on most labels. Sublingual delivery, not a swallowed tablet. And the rest of the B vitamins alongside it, because the research is clear that B12 doesn't repair a nerve on its own, it needs B6 to settle the misfiring and folate to finish the job. So now I had my checklist. Four things, non-negotiable. The active form, methylcobalamin, not cyanocobalamin. A real dose, around 5,000 micrograms, not the few hundred hidden on most labels. Under the tongue, not swallowed. And the rest of the B vitamins alongside it, because the research was clear that B12 doesn't repair a nerve on its own. I went through the shelves the way I'd go through a drug chart. And almost everything failed on at least one line. Right form but a swallowed tablet. Sublingual but underdosed. A decent dose but the cheap cyanocobalamin. One after another, crossed off. It took me weeks to find one that ticked all four. Active methylcobalamin. A real 5,000 micrograms. Sublingual. Full B complex. And third party tested, with the certificates published, so I could read the actual assay instead of trusting the label, which after everything I'd just learned, I was never going to do again. It's called Olvexa. And crucially, you keep taking your metformin exactly as prescribed. It's doing its job on your blood sugar, you never stop your diabetes medication. You're simply putting back, in a form that reaches your nerves, the B12 it's been draining all these years. I've used it myself, every single day since. And I recommend it to nearly every diabetic patient I see with nerve damage who tells me the tablets never did a thing. Why? Because it solves the problem the bottles never even admitted to. It gets the B12 past the stomach and the liver that were destroying it, past the intrinsic factor that stopped working, and delivers it to the nerves that have been starving for it. It does what swallowing a tablet never could. My next appointment was in five weeks. This was my last chance before the prescription pad came out. The bottles arrived on a Tuesday. I took the first dose that night. A dropper and a half under the tongue. Expected nothing. I'd been disappointed too many times. I'll be honest, the first week was quiet. Nerves don't turn around in a few days, and I knew that. I kept going. One week in: the burning that usually hauled me out of sleep at 2am came less. I got more of the night. And the evening burning that used to sit at a 7 out of 10 was down to about a 5. Two weeks: My daughter rang. "Mum, you sound different. More like yourself." The tingling was around a 4 out of 10 now. And it wasn't spreading anymore. Three weeks: I could feel temperature again. Hot and cold on my feet, sensations I'd started losing, were coming back. The evening pain had settled to about a 3 out of 10. Four weeks: I went to my appointment. The GP did the filament test, the one where they touch ten different spots on your feet to check sensation. Last visit, I'd felt 3 of the 10 points. This time, I felt 7. He looked confused. Checked his notes. Did it again. "Carol. Your sensation is, actually, improved. That's unusual." I told him. The sublingual B12. How the nutrient was never the problem, how a swallowed tablet just couldn't carry it to the nerves in my feet, and how the metformin had been draining it the whole time, and how taken under the tongue it finally got through. He typed notes. Nodding slowly. "Well. Whatever you're doing, keep doing it. The progression has stopped. If anything, you've regained some sensation." He closed his laptop. "No need to discuss medication today." No gabapentin. No prescription. No brain fog, no weight gain, no dependence, no watching myself slowly become the patients I've cared for all these years. Just "keep doing what you're doing." That was six months ago. The tingling in my feet this morning? Still there in the background, but stable. Not spreading. And my sensation keeps slowly improving. I check it every week now. Not out of anxiety. Out of gratitude. The progression has stopped. Week after week. No medication. No side effects. No watching myself slowly disappear into the fog I've seen consume so many patients. Here's what I want you to understand. If you've tried B12 for your feet and it didn't work, it probably wasn't you. It probably wasn't that your body is different, or that you're unlucky, or that natural solutions just can't compete with medication. It was probably that you were swallowing the right nutrient in a form your body broke down before it ever reached your feet, while your metformin quietly drained the rest. Your nerves never got a real dose of what you were paying for. You were doing everything right. The B12 just never arrived where you needed it. And every month you spent on tablets that couldn't get there was another month of your nerves starving. Another month of the numbness creeping a little further up. The nutrient is real. Methylcobalamin's role in diabetic nerve health is real. The only thing standing between you and it was a delivery method that was never going to work, and a drug draining it that no one told you about. Taken under the tongue, it gets through. Past the stomach. Past the liver. Past the failed intrinsic factor. Into your blood, and from there to your feet. But only if the form is the active one your nerves can use. And only if the dose is a real one. Olvexa is the one I've found that gets both right. Active methylcobalamin B12. A real 5,000 microgram dose. The full B complex the nerve depends on. Sublingual, straight into the blood. Third party tested. No fillers. Taken alongside the metformin you keep. 👉 https://tryolvexa.com/products/olvexa-vitamin-b-complex Right now Olvexa is running a promotion with real savings. But they're a small company. They make everything in small batches to hold the potency of the actives. When they sell out, it's usually weeks before the next batch is ready. 90 days to try it. Nerves rebuild slowly and the best of it comes in the second and third month, so give it the full ninety. If nothing changes, full refund. No questions asked. But if it works? If you take it tonight and by week two the 2am burning stops waking you? If a month from now your GP is checking their notes twice because your sensation has improved? If you're finally living without watching the numbness spread and the medication deadline approach? You'll wish you'd started fifteen years ago. I know I do. 👉 https://tryolvexa.com/products/olvexa-vitamin-b-complex You don't have to keep swallowing tablets that never reach your feet while the medication you're afraid of waits at your next appointment.
