"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."
