I have 2 OC's left and needs some more oxy. I also have some (Endocet, I think) pills that are 10/325, oxy/acet. So how bad is it to IV acetaminophen? And while on this subject how about IV aspirin or ibuproffen? Fast responses greatly appreciated! P.S. I am reluctant to try a CWE due to a failed attempt in the past that wasted a bunch of material. Now I am scared to try again for the same thing may happen.
