I could never, EVER do that. Most the times I've ever been awake at that hour were because I hadn't been asleep yet. (I.E.--the 70's/80's) My company of the last decade or so doesn't care WHEN I shop up at the job site (within reason) I don't sleep well, out of 7-8 hours I probably get 3-4 hours of good sleep, always wake up feeling like crap. I DO have to show up at 7am now and again, it's hell and a lot of coffee
