pain
"I started taking this medication several years after a failed back surgery.  Regular pain medicines did not last long enough to allow me to sleep more than 2 hours at a time, so my MD said I could try the patch so the pain medication would last for a longer period.
As far as pain control I would say the patch worked very well.  I was just using the 25mcg/hour strength and I started being able to sleep for 4 hours at a time, so I was happy about that although 4 hours still wasn't great.  

I did not ever have any feelings of euphoria, I just felt "normal" finally, and was able to get some housework done that I could not do before because of the constant back pain.  I did have some break-through pain that was relieved with Motrin or Lortab."
