Me too been on both for a few years Gabapentin for nerve pain doesn't help much with the neuropathy mine it did improve after I started taking the metabolic prepared L-Folate to process B vitamins my levels of B6 and B12 were off the charts high because I have a gene that lacks the enzyme to process B6 and B12 so I had B vitamin toxicity which ironically has the same symptoms as low B12. Good luck with your journey.
