bipolar disorde
"I was put on Wellbutrin for smoking cessation, I had zero personal or family history of any mental health issues.  The Wellbutrin did not work for smoking cessation, so my doctor took me off it abruptly.  I suffered from the common on the Internet, but completely unheard of by doctors, Wellbutrin withdrawal symptoms of "brain zaps" or "brain shivers," odd sexual side effects, and powerful dreams.  These adverse withdrawal effects from Wellbutrin were then misdiagnosed (according to the DSM) as bipolar.  So in my case, Wellbutrin withdrawal effects were the etiology of a bipolar misdiagnosis."
