I dose 20 mg oxycodone a couple of times a day. I'm out and only have 15 mg extended release morphine pills. Based on my normal oxy dosage, how many morphine pills should I take? I know 30 mg morphine should be equivalent but last time I took that, it just made me sleepy and I didn't feel pleasant at all. And yes I know it's not going to be the same no matter what dose I take because it's ER but just trying to find something to at least make me comfortable. Is there a way to bypass the ER? I don't mind it but would prefer to have IR effects if possible.
