10 yrs.ago given this med.after botched surgical procedure.I have always abstained from alcohol & tobacco. I have stage 2 rectal cancer and am highly motivated to stop because when the time comes, I will need a system that can have pain med. uncompromised. I have a home to run, etc. so can't be "down" for more than a day. I know I can do this if only I had some guidelines. If anybody could help or direct me somewhere, I'd be so grateful.
