There may be possibilty of some type of drug reactions if those 2 medications are mixed. Ive heard a lot of stories about it too. I dont take it, and because of the stories ive heard i probably never will. It wont be so bad if you wein off it slowly, i would assume. Talk to your doctor, and find out what is truely best.
I am a panic disorder patient and I have taken wellebutrin and while it did not work well for me, it has worked extremely well for many of the members of my panic disorder chat group. Trust your doctor to make the right decision and if that does not work ask for some klonopin to go with it. Remember I am not a doctor and this is only personal experience and not a trained medical advisement. I amjust a patient.
