Since I've been back at work, I've developed the most middle-aged sleeping habits. I've been going bed between 11-12pm (last night 10:30!) and getting up between 7-8am. I'm talking about 8-10 hours every night. This sounds like a good thing in theory, but now if I try to stay up past midnight on weekends I'm dead on my feet. Maybe it has to do with the fact that these days, given the choice between being awake and sleeping, I'll pretty much choose sleep over anyone or anything.
