Tramadol
"My dentist perscribed Tramadol yesterday because of an abcessed tooth.  I see an Endodontist this morning.  It helped with pain, but I have not slept one minute all night.  My mind raced all night.  I was so sleepy, but if I closed my eyes I had movie like images racing.  I have never been on any kind of "speed" but I feel like this is what it would be like."
