Aloha Joecarver, How is r lipoic acid different from alpha lipoic acid? I just ordered alpha lipoic acid and benfotiamine on iherb.com. should i have gotten r lipoic acid? I started gabapentin 2 or 3 weeks ago and feel slightly better, but i don't know if its that or cutting sugar from my diet I am newly diagnosed and would appreciate any advise. thanks, Debbie
