Yes, like hell. The codeine should get cyp2a6 going, and once the codeine fully converts, the oxycodone will take its place and be converted to oxymorphone. Take the codeine first.
I have 10 mg percs and 30mg (3M) codeine, 30 mg codeine phosphate and 300 mg tylenol. Trying to get the most out of the percs, and keeping and eye on tylenol of course..
