I took it almost a year. It DID help me, and of all the side effects, the tingling and numb sensation was the worst for me, it never subsided the longer I was on it. The only other effect it had for me was making cold drinks feel hot in my mouth, no matter how cold they were. Sweet Tea and chocolate milk were the only 2 things I could drink while taking it :( .

Topomax worked the best for me, but I had to come off of it because it gave me kidney stones (twice) .... one of the side effects! As bad as migraines, but I didn't want both!
