I was on Wellbutrin for (starting at age 8) 11 years 150mgx 2 , starting when it was first introduced. The common symptoms I experinced while on it were extreme anxiety (Panic attacks), irritability, vision loss, weight loss, zombie like trance and trouble sleeping. The doc just put me on another SSRI to counter these effects...
I'm sure its a great drug if you need to quit smoking but why take something for depression that you're going to have to take another anti-depressant to counter act? Oh and since Wellubutrin is a BIG stimulant watch out coffee, cola, cigarettes, weed, etc.
