Topiramate
migraine prevention
"I've been on this medication for about three weeks.  It has helped with the migraines...I don't have as many episodes, and when I do have it, it's not as severe.  Haven't experienced any bad side effects.  The one side effect (which seems to be the most common) is appetite suppression, change in sense of taste, and constant thirst.  I haven't lost much weight in three weeks, but I have a feeling the longer I'm on this medicine, the more I will lose.  I guess it's a good thing."
