I used to take Topamax, then freaked out thinking it interacted with my birth control. Havent gotten a straight answer from a dr on that. I lost like 20 lbs when i first started it. I still had some migraines, but not as severe. Then my pdoc prescribed it for my mood swings. I didnt think it helped much, but after a year of being off it, i see a big difference. So i hope i can take it again soon.
