I have been on topamax for about 7 months now for migraines && im about to get off of it. Im 18 years old and "trying" to do college but ive had so many side-effects its crazy. I cant go to the bathroom w/out taking laxatives cuz i just cant go ne more i literally have to take something everyday or i will be stopped up for a week or more. Ive been depressed and my anxiety has gotten worse.I take 150 and they want to put me up to 175 but i refuse because ive heard of people losing their hair taking it especially when they have a b12 deficiccency...which i have. I have horrible mood swings i can be happy one minute then sad or mad the next and i never used to be like this. Ive now started getting my migraines back so im stumped on what to do. I cant word things right....i was trying to say i didn't like something and instead it came up "im not to high"... yea so its deff a crazy drug but it can work for others and not. Not for me!
