Hi Jim, Sounds like we have pretty similar conditions. I'm also currently taking 1500/day of Gabapentin. (I was up to 1800/day, but was doing better - so I went down to 1500, then tried 1200. At 1200 I found out pretty quick that the Gabapentin was in fact working after all - so I went back up to 1500.) I'm also on a pretty broad supplement regimen.

As Ken said, you seem to be headed in the right direction. If you want to up your game in the supplement department, you might want to consider taking some magnesium (an absorbable form, not Mg Oxide), and benfotiamine as the next steps. (Magnesium is good for general nerve health, and many people get significant pain relief from benfotiamine - a stronger form of thiamine.)

The one thing you should try to do though is add the supplements in one at a time, so you know what they are doing for you (if anything). I kind of did the shotgun approach, now I'm not sure which are helping and which aren't.
