I take it for migraines - it's no surprise it would affect your mood it's used for
seizures, bi-polar, and depression too. Maybe you had some anxiety
, and the Topamax just took the edge off. I taken 200 mg. for quite a long time, haven't lost a pound, and it hasn't altered my appetite, but that's not what I'm taking it for - although I sure wouldn't mind losing weight!
