Avandamet is an interesting drug. The side effects of one portion is weight gain - I think that is the Avandia. However, the other portion can sometimes have the effect of an appetite suppressant.

Avandamet actually made me gain ten pounds in about a week. I lost it almost as soon as I gained it. But, I had a lot of initial side effects on it, that went away within a couple of weeks.

Still, try to see if you're eating less than you have been. That could be the culprit. :)
