I have had epiderals, therapy, chiropracting,and tried these things many times to no avail. Darvocet has helped e alot. I take it every four hours while awake and no problem sleeping. I am having Spinal Cord Stimulation next month and need to know how to get off the darvocet... Can I just quit if the procedure works. Any response would be helpful. Thank you. Peggy Carman
