Since November 2007, I have had a handful of random episodes of near syncope (
fainting). I have always been a migraine sufferer, but from August 2007 through June 2008, I was taking Topamax as a preventative migraine medication (50mg once a day). Topamax, in higher doses (about 200mg), is mainly a seizure medication. I had not experienced such episodes until I began Topamax, but it did its job in preventing my daily headaches.
