The last time I tried to stop mine (Bupropion/Welbutrin 150 mg per day)--I had horrible headaches (I hardly ever get headaches), was dizzy, lightheaded, nauseous, and lethargic. No wonder I am still taking it.

In retrospect, I wish I had tried a therapist before a psychiatrist. Sometimes I also would like to try having a chemical free life (with the exception of coffee--don't really want to give that one up...)
