As mentioned above, Wellbutrin is not known to add weight; in fact, may help control appetite. It works on a different brain chemical than the SSRIs. I do not have trouble going on or off Wellbutrin. This is my second time on it.
Zyprexa and Depakote definitely make me extremely hungry. I am now off Depakote, thank goodness, as it was the real culprit. I only have to take Zyprexa as an anxiety rescue medication so don't have to deal with daily hunger from it.
My son, friend, and I all gained 50 lbs on Paxil. And the literanture says weight gain is not a major side effect!
I think it's so sad that we have to deal with anxiety AND weight issues as well.
