Bipolar Disorde
"I had the worst side-effect from this medication.  I was originally prescribed it about a year ago for insomnia related to my Bipolar 2.  It worked to get me to sleep, but eventually I started to have enormous amounts to rectal pain, so I went off of it when I stopped cycling.  I was put on it again this year when my cycling started again, and I again had the same pain.   It was absolutely awful.  So I am off of it now and never want to be put on it again."
