i know most all epileptic medicines have weight gain as a side affect, I am currently taking topamax but it is a failure for me so we are having to switch from this. I took tegretol before this and i had weight gain from it, is there a medicine out there i can ask for to switch to and try that weight gain ISN"T a issue with? i know side affects for these are nightmares and this might seem like a silly one to worry with but for me it is something that concerns me. thanks!
