Nucynta
"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'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't breathe, and get anxiety. It doesn'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't get up in the morning to go to work. I will give it more time to see if it gets any better."
