this is no where near equivalent to what you were taking....hopefully she left you with the percs for break thru pain; and this was for MScontin, correct...ie sustained release morphine??...there is a 2/3 ratio between oxycodone and morphine....you need half again as much morphine as oxycodone for the same pain relief.....if you were taking the max of the percs you were taking 60 mg of oxy a day.....so the 30 of morphine is going to be spitting in the wind.....GOOD LUCK
ps the sustained meds are best given in 8 hours increments, not 12; especially in the younger person with the faster metabolism
