I, too, have my "days and nights mixed up" and I read somewhere that there is a name for this. Can't recall it right off hand. I take meds for insomnia, but on the occasional day when I have to get up for some reason [I am now disabled and not working - not as neat as it sounds], I skip the insomnia meds, and am better able to get up. But I don't think you are talking about meds. I know the feeling of not falling asleep until the wee hours and then feeling as if I were anesthetised, once I do fall asleep. I don't know how to reset this clock, but I agree with you on the Red Bull! If not for that, all of us with this backward sleep schedule would probably be disabled!
