Help! Taking 3 3/525 percocet a day and no longer feel effect. What can they increase to and how much oxy and acetomenaphen is too much. I have increased it before doc appt to get relief. I don't want to OD but what is the maximum amount of the oxy or the acetomenaphen before you will OD? I've doubled this amount tonight. I know I'm not close but still need to know maximum maybe to tell the doc if he hedges on increasing. Also was taking Tramadol 6 50 mg a day before Percocet and that amount stopped working. Can I take more Tramadol? Which is safer? Lifts your mood overall. Not like a high? Thanks!
