"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 was taking this med. for anxiety and depression.  i cried every single day, and several times a day on this med. and i did not sleep a full nights sleep for the entire duration. 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&#039;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"
