5 hours sleep is not enough. Had to be up at the crack of dawn for a doctor's appointment. He was running late, so I sat in the waiting room for about an hour. This meant that by the time I got home, I'd been conscious for long enough that I couldn't get back into bed and fall asleep again (I tried, it didn't work). So now I'm tired and bad-tempered, and I need to get dressed and go to work, except all I really want to do is sleep.
