I currently am scheduled to have major surgery. I was on Methadone for several years before Suboxone. I thought I wasnt ever going to need to take pain meds again but they say that the Suboxone will not be sufficient enough to handle the post-op pain. Time is creeping up and i know i need to stop, but how long? What's the minimum amount of time I dont want to get sick or even stop breathing!! :(
