Pain
"I could not deal with the side effects of Oxycontin or hydrocodone.  Too much dizziness and severe itching.  Unable to get restful sleep.  Nucynta ER 50 2 times a day has been MUCH better for me.  Very little side effects and only for the first couple of weeks.  I sleep better too.  Only objection is that it wears off after only about 5 hours.  So I have to take hydrocodone occasionally."
