depression
"Terrible med. for me like it was for a lot of people.  I used it for 6 weeks (enough time to get into my system).  It caused panic attacks, which was not fun.  I would have several each day.

I felt way more sad, and felt like I was in a zombie like state daily.  I read reviews of this drug and prayed that I would soon start to feel better, and wouldn't be one of those that this drug did not work for.  Alas, I was one of those.  I stopped taking Effexor, cold turkey 5 days ago.  Best thing I ever did.  I experienced some withdrawal symptoms, like severe brain zaps"
