Glas symptoms and conditions

I've been taking Topamax now for about 6 weeks, and my headaches are still just as bad as ever, except now I have headaches with the thrill of numb fingers, confusion, weight loss, memory loss, an absolute horrid taste in my mouth, and now the latest.... my hands feel dirty all the time. Has anyone experienced this?? I just feel like my hands are dirty. I wash them, and a half hour later, it almost feels like there's a film on them, and I have to wash them again. Almost ocd-ish. So 6 weeks in.... Anyone have any advise on how much longer I should give this topamax before I give up on it & try something else? My doc said it should have worked by now if it was gonna - but I have read on here, that it sometimes can take months...? I just don't know if I can take these side effects, AND the headaches for much longer without going NUTS! {grin}
Any advise?
