The worse part of chronic pain meds is learning you must have  surgery..  It has happens to me that doctors are afraid to kill you will medicine .  they do have another opinion 'Pain does not kill you'.It can however wish you were dead, and you beg someone to kill you.  After 30 surgeries i have some personal knowledge.  I  gave up my pain doctor and all his morphine and the other big 2 schedule medicine,   To be honest  i also stopped smoking after 40 years.at the same time.  I always heard cigarettes  harder to kick than heroin !!  in my case { the ms contin had to be the cousin of the H.}  for me it was also is a fact.. i miss and dream ,think of cigarettes . all day every day.  six months after saying goodbye it still consumes me .                                                                                                                        i just want to know when my body will adjust and normal surgery meds will work w/o a tolerance ?
