Hello Dr. Grief, I recently had very painful surgery for sleep apnea. Jaws sawed in half. I 'm not happy to hear of Norco. I bear my back pain .I'm hopng Dr. Does not::put me on This after the pain l've been through. I only need one more and I'll be fine . I feel why not listen ,paitent prefers at 53yrs To use what's been working for years. I am speakng of short term use. I'm upset To even go. Surgery is over.It's like ok done wth you. Try this new drug, its the same & how paitent feels, who cares? Karrie Rbchaux
