Tramadol
"I didn't know anything about this drug and was on darvocet when my workmans company suggested I switch to this. It was a little weak at first but then I got it into my system on a regular basis and it seemed to dull my pain. Both heels were crushed in a fall and I had reconstruction surgery. This does make me sleepy and is terrible to get off of. I had every symptom of withdrawal listed. I had to call my doctor back and be put back onto it. BEWARE."
