Tramadol
"Worst stuff around.  Do not take this stuff! Doc started me out with 50 mg two times a day.  Wasn't relieving my pain, so got pushed to two pills every 6 hrs. It only take away some of the pain. When I wanted to stop taking the pills I went through 4 days of awful withdrawals even though he told me I wouldn't have them.  I hate that doctor now. I'm going all natural for the pain."
