I have IBS"D" but I also have a lot of back problems. I have a degenative disk along with 2 spurs in the same area. My Dr gave me a new pain med. It is called Darvocet. It helps with the pain better then what I was taking before and one of the side effects is constipation. Has anybody here on the board used this med for pain? I read on the readout that came with it that it could be habit forming. I'm supposed to go to a pain clinic at our hospital and probly end up getting a shot in my lower back. I'm not sure what I want to do, the shot of take a chance on a pain med that could be habit forming. I have read that lots of people get problems on these pain meds. Taffy
