obesity
"I was on Topamax for almost 3 years, was prescribed it for severe migraines. The weight loss was a side effect, a nice one though! I didn't need to lose much to begin with, maybe 20lbs or so, and I started to notice that I went from the 140's to the 120's. I am now off this medicine as I have been migraine free for almost two years and the only bad thing I can say is that the weight comes right back on if you're not watching very carefully. Also - HUGE side effect was the medicine caused my body to not sweat, which caused severe overheating. It's a less common side effect, but a very super important one to be aware of."
