I would cut down the Wellbutrin over a 2 week period. I tried cold turkey once and just wanted to cry for no reason. But weaning yourself off it should do the trick since you don't want to be on it anyway. The advice of asking your Dr. is good but like you said alot of them aren't in the picture, so to speak. You will figure it out by the way you feel. Maybe every second even. Just a thought. Good luck and happy cleansing.
