What was his reasoning for not letting you take Wellbutrin?? I'm just personally curious, because I just recently started taking it, and I'd be curious to know what your doc's hesitations about it were..
For the record, though, I am also on Lexapro, and have been on it a while, have not gained weight or noticed that I craved food or felt hungry any more than usual (oddly, I seem to be feeling more hungry since starting the Wellbutrin!! but I think that is rare, and might be due to other factors, not the medication)
