Topiramate
"I've been using Topamax for about 4 months after suffering for about 20 years.  The migraines had started to come every week and I couldn't function for days.  This medicine allowed me to function again without having to worry about when the next big headache was going to come.  Side effects haven't been too bad, some tingling, and I can no longer drink anything carbonated, but well worth it. "
