"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."
