I lost weight when I added Wellbutrin and Seroquel but, otherwise no weight change with Lamictal. I was on Lamictal for at least a year before adding to it. It isn't suprising I lost weight with Wellbutrin, antidepressants always do that to me!

If your appetite has returned, it is likely just that especially if it is a mood equals appetite level situation. See what happens when you go back to your "normal" weight.
