thats interesting what you said about morphine tolerance !!
did the nurses/doctors just think you were a wimp ??
i had the same thing last year, i had an operation, and they had to pump me so full of morphine i was totally tripping.....they were accusing me of a low pain tolerance, but its not true because ive had operations on my testicle and eye (very sensitive areas!!!) and the nurses then were saying i had good pain tolerance, i even was refusing medication then.
do you smoke cannabis ?? i was smoking a hell of a lot in the year leading up to my op, i was wondering if it had any effect ??
i know morphine & cannabis are totally different but they affect endorphine production apparently......
or mebe we are just almost immune to morphine for some reason....
