Another tip is too never treat to the point there is no pain, once you reach the feeling good/euphoria level it's over. They are to make pain bearable not turn you into a slobbering idiot.

That was exactly the reason for my above question to Doc, I got busted up really bad a few decades ago and was home healing after a spinal fusion surgery, they gave me some dosage of oxy something.
I was at the point of slobbering down my shirt sitting in a chair and starring out a window all day, I called the nurse and told her so, she laughed and said for me to break the tablets in half and take as needed, I still can't imagine how someone could get hooked on that feeling, or in any case like, and want to be there.
