I have been taking Wellbutrin for almost 2 yrs. I stopped treatment for a period of 3 months during that time but resumed almost a year ago. I have recently been weaned off the drug and have noticed a 10 lb weight gain. While my diet has not been of the healthiest choices at times during this stage, I have worked out everyday for 45 min of cardio so I am surprised to see weight gain. I have never gained weight at this rapid pace before (except w/in the first month of taking cymbalta- which I stopped b/c of the weight gain) no matter what I have been eating. Is this a normal side effect of going off the drug? This has all taken place in the matter of a few weeks to a month it seems. Can you tell me if weight gain after discontinuing the drug has been a common side effect for others?
