I've been on Topamax since 11/05 for migraines. I had the tingling in my hands/feet and soda tasted off but that went away after a month or so. Then about April I notice I was losing alot of hair and I started having migraines again. I've increased the dosage to 150 mg. I'm not sure I want to stay on this with the hair loss. I was glad to see that I'm not the only one experiencing hair loss. I didn't know that was a side effect until I started doing some research.
