Hello Hello~Kitty :P
As with most migraine medications, topamax can give you headaches. I'm not sure if it's because it dulls the migraine so much that it just feels like a normal headache, or if the medication actually causes headaches. I never had any problems with topamax, but I have a friend who experienced dry-mouth and headaches while on it. She stopped taking it right away, so I don't know it the side effects would have gone away with time or if they would have continued if she had decided to give it more time.
I hope this helps somewhat,
