I've taken oxycodone in the past for back pain. I don't recall every feeling overwhelmingly tired. I am currently taking hydrocodone for dental issues and I feel like my eyes are about to fall shut most of the time! The drive to/from work is very rough. I never felt this way with oxycodone, but it doesn't seem reasonable to me that it would make me less drowsy. I am thinking of asking for oxycodone on this basis but afraid the Doc with think it's BS. Any opinions?
