Hi folks... I was just given Morphine sulfate IR, 15 mg, up to 2 every 4 hours. It's not helping that much with the pain, but i don't want to give up. I have a feeling this is a much smaller dose of pain medication if I'm right looking at one conversion chart? It was confusing, but it looked like if I took 120mg a day of Oxycodone the dose of Morphine Sulfate would be at least 250mg a day? ANYONE?
