I have been on topamax for migraine prevent and wow the difference is amazing!!! I started off at 25mg then bumped it up to 50mg. I don't get the tingling or anything, but i did notice that soda taste weird so now I will not drink it (which is probably a good thing in the end) and I have been nauseated since valentines day and I started the topamax on the 10th or 11th, i only got physically sick once but I have to make myself eat. Unfortunately, I have not lost weight like I wanted (i'm 20lbs overweight) but I am not gaining weight either. Has anyone else experienced this>
