"in january 2009, i was prescribed dilaudid 8mg (2 tabs 4x/day) to battle break-through pain, in conjunction with my constant regimen of oxycontin 80mg (2 tabs, 3x/day) therapy. it was as though i had been given a placebo. no effects - neither positive or negative. i have a high degree of opiate tolerance, which renders pain management a difficult chore. my doctor switched me over to morphine sulfate immediate release back in august (30mg, 2-3 tabs/every 3-4 hours), which (to my system, at least), is far more effective, despite the fact that dilaudid&#039;s efficacy is about 6-7 times that of morphine&#039;s."
