The 3 most successful methods is Benfotiamine (Fat Soluble B1)(200-300 mg), Stabilized R-ALA (200mg - 300 mg per day) and Sublingual methylcobalamin Maybe try these all for at least a couple months. Hell, I would try all these at same time for 6 months but they will work in most people within 2 months.
