I was on Cymbalta and I gained 25 pounds even though my pdoc insisted it was not the Cymbalta. I am in the middle of switching to Wellbutrin and weaning off the Cymbalta. I have dropped 5 lbs already.
During the weaning process it is hard to tell is my feeling a bit off balance is due to the medication change.
My dose of Wellbutrin is 150 mg 2 times per day.
Hope this helps.
