Depression
"Before being diagnosed with Bipolar Disorder, I was on this antidepressant, along with Zoloft.  It gave me manic symptoms, so beware for those who may have undiagnosed Bipolar.  Plus, on 300 mg, I felt terrible, as if I was sped up.  Physically, it made my heart race and caused agitation.   Lowering the dose to 150 mg was better physically (before being diagnosed by Bipolar, but then I was taken off of it completely).  Whether on 150mg or 300 mg, I noticed insomnia.  I have also heard other people say this who aren&#039;t Bipolar, although I&#039;m sure for some, this works wonders."
