Ok I have never taken morphine before and I am asking this so I do not wind up in the ER..First of all I don't understand those conversion charts at all nor trust them so here is my question..I chew up 150mg of oxy at a time to get where I need to be..Anything less then that I don't feel a thing..I have 240mg of morphine oral (four 60mg pills) if I chew them all up at once will I most likely keel over? or will I not feel a thing and just waste it...Today wouldnt be a good day for a hospital trip..Not that any day is.
