the above calls for injection of vitamin b1. if you cant do that then look into benfotiamine, which is a fat soluble version of B1 and is readily absorbed by the body. you can buy it many places on the web.
also, be sure to get plenty of good fat. flax seed oil, fish oil, borage oil, and high quality butter are all key. eat fatty fish like sardines and take some lecithin. those nutrients will help the nervous system to regenerate.
