migraine prevention
"By the time I started Topamax, I was getting migraines 2-4 days a week. Topamax seemed like the best fix. And for a while, it was. My migraines significantly reduced, though I did get most of the common side effects: slight tingling in my fingers, carbonated beverages tasted gross, and weight loss. 

My main warning about this medicine is weight loss. It seems to be paraded as a benefit, and to some it may be, but if you are already naturally slim, pay very close attention. I wound up dropping to an unhealthy weight despite all attempts to counter it, and it's ultimately why I had to stop Topamax. I was unwillingly wasting away. When I stopped, my migraines returned in short order, and I'm still looking for an alternative that works."
