migraine
"My neurologist put me on this after being on Topamax and propranolol for chronic migraines for 5 months. For the first time in 6 months, I haven't had a headache for 3  consecutive days and it's a miracle! Only thing is that I've been excessively thirsty and having some problems with my vision/dizziness, but she warned me that I would likely experience the dizziness. Such a change in my life."
