I'm also non-diabetic, but have had PN since 2000. Gradually, I've been eliminating the things I used to eat: night shades, gluten, sugar, and now I'm thinking of the Paleo diet. I also have added Methyl B-12 (from 5 mg at first and now a maintenance dose of 2 mg) daily. Going gluten free was a big help, but I need more--maybe grain-free. There are lotions available which contain menthol that will help with the burning. Read MrsD's posts--she offers excellent advice and I think you'll be able to see a difference if you follow her suggestions.
