Topiramate
"I started taking Topamax about two and 1/2 weeks ago. In that two weeks I've lost close to 10 pounds.  I've also had the tingling in my fingers and feet and toes. I've gotten tingling in my lips too. Other then tingling body parts, so far I love it and Ive gone from headaches every day to maybe 4 really small ones and one migraine."
