i have been taking topamax for about 6 weeks, so far it has not been too bad. The worst thing was the first week when I though I would die of heat. I looked like an idiot at work. I had a paper towel around my neck with ice cubes in it. Luckily it only lasted about a week, I still get hot every once in a while but not too bad. The taste has changed as well, but that means diet soda is not so bad so maybe I'll lose even more weight. I am nausea sometimes, but overall the side effects have not been too bad. Luckily I have not had the numbness and tingling. I want to wait out the side effects because from everything I have read the full effect doesnt take effect for at least 2 or 3 months, so try and wait it out, if it works anything is better than the migraines!!!!!
