Topirimate symptoms and conditions

I am on my second time around with Topiramate (generic Topamax). It has been a year, and I have no reason other than weight loss to take this drug. I also don't know if the online generic versions are really Topamax except I do experience some of the side effects I read about, the tingling arms and legs, the itching, and the foul tasting carbonated drinks. I have started at 25 mg. per day 3 days ago, and am at 250 mg today with no cut in appetite except an hour after I take the pills. Do you think they are even real?
