When I think about giving 10MG, to start, in post surgery recovery. Very different situation, of course. Have actually moved more toward Fentanyl- normally an anesthetic drug. Just 2.5 of MS does seem meagre, but then, you need them to answer questions? OR just so you won't have enough on board to tempt the junkies? Very true that all the pain drugs work differently on different people, all can cause nausea, previous narcotic use dramatically decreases effectiveness, as does smoking. Morphine is good for the MI.
