I started using Celexa (40mg) in 2009, with no side effects. After surviving cancer, I was depressed so my doctor added Wellbutrin, about a year ago. Since then I have gained at least 10 pounds. I eat healthy, exercise 4-5 times a week but can't lose the weight. It seems likely Wellbutrin would be the cause, but I thought it was weight-neutral. I want to wean myself from one or the other, but not sure which? Is it possible that the Celexa has caused weight gain recently? Or should I stop taking Wellbutrin? I will consult my dr., just wondering if anyone has any thoughts?
