migraine prevention
"I have been taking Topamax for about 6 years now.  My current dosage is 200mg/day - the dosage was recently increased during a high-stress time. The main side-effects I notice are slight tingling in fingers, which only lasts a few moments. I have gone from 5-6 migraines a week to only 1 or 2 a month. Certainly worth it."
