seizure prevention
"I've only had a seizure once, but I take it for seizures and migraines.  I am getting off it.  I take 400mg a day.  The side effects are too much for me. If this works for you and you are on a smaller dosage great. It's made me suffer the entire time I have been on it, granted I do take a higher dosage than probably most of you.  I do have to admit, as far as migraines go, I haven't had as many and I normally do."
