I had some slurred speech and the fat tongue feeling on Gabapentin too. Now I'm back on a very low dose of Lyrica instead I'm not getting it at all. My pain doc described Gabapentin as 'nasty powerful stuff' I also had a lot of gastric problems with it and personally would never go back there again. I know it works well for some people, but sadly I'm not one of them!

I really hope your symptoms ease soon, sounds horrible to have to deal with. Take care and good luck.

Bram.
