--a few people who've reported good results with Topamax in the past, and a few others who said it didn't do much.

Topamax has an interesting side-effect profile compared to the other anti-epileptics though--it's the only one I know of in which weight loss, rather than gain, tends to happen. Doesn't seem to promote the carb craving that Gabapentin, Pregabalin, or some of the others do.

One other thing I should mention--people with high eye pressures or pre-glaucoma have to be very, very careful taking Topamax--in fact, it's usually contrindicated, as it seems to have the effect of increasing said pressures. (People with glaucoma are warned away from it.)
