Permanetly symptoms and conditions

I have been on 100 mg topamax for a few months now, and i was actually having people try my drinks bc i thought they was flat, and i would feel my fingers and my toes go numb and tingle. I honestly never thought for two seconds it was my medication. The only side effects i was warned about was weight loss (which hasn't occurred with me) and that i would be very thirsty, which i am. But i have NIGHTMARES about things im not even afraid of, and i have trouble spelling words i didn't before, and sometimes i can't even remember what i wore last week to school. Im starting to rethink this whole topamax thing, does anyone know any other prescriptions that will help headaches without the crazy effects?
