Now opiates work on your brain, it is meant to cause
euphoria to make you not care about the pain, that is how it works, but because of the taboo, Dr's and patience are reluctant to talk about that. Why? I mean I read all the time about "it doesn't make me high, or euphoric", but if it is not it isn't working right, yes there is tolerance, and when the euphoric stops it works less. Also the sleepiness and drowsiness all are made to make you not think about the pain.
