pain
"My experience with Nucynta was very dis-appointing. Did not relieve pain any more than a few ibuprofen. And it made me feel tired, sleepy. I have been on many pain medicines in the quest to find something that allows me to function. This one will be at the bottom of my list, mainly due to it's poor performance for me in easing the pain / combined with sleepy, tired and a little dizzy."
