I'm giving up on Gabapentin. I am thinking of asking my doctor if I can try topamax instead. It is an anticonvulsant, like gabapentin, but it works differently. My husband started taking it about a year ago for bipolar disorder, on top of his Paxil, and he went from 40 pounds overweight to normal weight within about 5 months. And it helps his mood swings a lot. But I don't know if it will help my pain the same way gabapentin does. Does anyone here have any experience with topamax, or know anyone who does?
