Some background info would be helpful, if you can share how long you've been taking the Norco, how much you're taking, and when was your last one? Did you taper off? Are you in active w/ds? What are your symptoms? Have you gotten clean before and relapsed?
Have you ever sought any kind of addiction help? While w/ds are most definitely unpleasant, actually the hardest part of recovery is STAYING clean, not getting clean.
