Topamax and yoga

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?

I am going to begin taking 25 mg of Topamax at bedtime tonight. After reading all of these posts I am a scared. I was prescribed Topamax for bipolar disorder. I am currently taking Lamictal as well. I always gain weight on psychotropic drugs and need to lose about 15 lbs (all of which I have gained over the course of being on Lamictal). Any who-my psychiatrist said that this medication may help counteract the weight gain I have experienced. Although I do not consider my self an overeater now. I do hope that it helps me to not like the taste of sodas though. I am addicted to Mt. Dew and caffeine, which I wouldn't mind stopping. Anyway, I am supposed to increase my dosage by 25mg per week until I reach 75mg per day. I am also supposed to go back and see my doctor before I increase the dosage beyond 75mg. I just hope I do not have the horrible side effects I have read here. Some of them I know I can deal with especially if they are temporary but the anxiety/depression/shortness of breath/lack of energy/morbid thoughts are the main ones that concern me. My psychiatrist said that with this medication I should drink plenty of water. He said that it could cause headaches and other side effects if I'm not sure to drink plenty of fluids with this medication. So, I am planning on hydrating myself really well today before taking it this evening. I'll post back and let you know how the side effects are going. Is anyone else on a combination of Lamictal and Topamax or on it for bipolar disorder? I'd like to hear more of your experiences.
