I have spinal stenosis, also a bleeding ulcer from taking naproxen and various other pain killers. Presently I rely on tylenol , hydrocodone and darvocet. When the pain gets real bad I use demerol, which is only slightly less effective than morphine. Please don't get me wrong, I use mostly tylenol and only use the others from dire necessity; the more dire , the stronger I use. Bob Anibal CG for Cecily 78/20
