pain
"Nucynta has worked very well for all my aches and pain, from the most severe to those I didn't even know I had.  At first, it did make me groggy which was a problem, but I kept taking it anyway because it did take away most of my pain.  After a couple of months of use, it takes away my pain, just like it did at the beginning, but I no longer feel sleepy.  I feel energetic, happier and am able very active because I hardly feel any pain.  I highly recommend it, but you do have to give it a chance because once your body adapts to it, the adverse effects far outweigh the benefits."
