Topiramate
"I was prescribed Topamax for chronic migraines 25mg 2xday for 5 days and then 50mg 2xday. Within 2 days, I had no pain at all, a more "stable" appetite with no carbohydrates/sweet cravings, and I had a lot more energy. The only side effects so far were frequent urination, mild leg pain/numbness, and eye sensitivity. By the third day, my eyes were so sensitive, I was constantly squinting and felt like I needed to wear sunglasses indoors. My vision has always been great and now I was having a hard time seeing clearly. In all the reviews I had seen, I never read about anyone having vision problems after taking this. I just want people to be aware of this happening. It did work wonders for my migraines."
