Pain
"Have been taking Nucynta for a few days. I was on Oxycontin with Oxycodone for break-through, but since the Oxycontin was changed in February to tamper-proof, it doesn&#039;t work very well anymore. When I take Nucynta, it makes me feel like a zombie, it only works for 3 hours for pain, when it is supposed to be 12 hours. I feel like I can&#039;t breathe, and get anxiety. It doesn&#039;t help me when waking in the morning from taking the night before like Oxy does. It seems everyone says to let it build up but it is hard since I can&#039;t get up in the morning to go to work. I will give it more time to see if it gets any better."
