Nucynta will keep you from feeling
withdrawal, it is a full agonist synthetic opioid, just like
methadone. Personally, I would taper down as low as you can before the switch. Methadone is very strong, and if I'm not mistaken, Nucynta is closer to a percocet. You will be okay, and the new child should lift your spirits. I agree with your doctor about the methadone, you don't want to stay on it too long. Let us know how it goes.
