Morphine / naltrexone
"The first day I took Embeda, I had no relief and was  badly in pain. But the second day, I woke up and felt great. It has really helped my pain. I've been taking IR meds most of my life, leaving me waking up in the middle of the night in huge pain - since Embeda that's gone away! I feel good, lot less pain, and am very impressed! Only downside - constipation and face redness. Otherwise it's great! And I'm only taking 40mgs with 4 Norco for rescue meds"
