I've been on Topamazx for about 3 months now. I have had a great deal of sucess for my migraines but am having to stop taking it b/c of Kidney Stones. Has anyone here had trouble with this? I'm really debating which is worse. I had 3 mig. a week before, and I had 4 in 2 months on it. but I had 2 occations with stones, multiple stones, and it was very very painful. Also, I am on 2 other meds. for migrianes so I don't know which one it was, but since being on the combo. I've felt I lost my "mental sharpness". Could this be the topamax as well. I ask you here only b.c it is a med used for seizures as well.
