I'm busy at the moment, but not so busy that it would be impossible to manage a reasonable seven hours of sleep a night. But I don't get anything even close to that. Getting to sleep is easy. Waking earlier than I really need to is, problematically, even easier.
This is a state I know very well from previous experience, especially when putting a show together. I'm guessing that some odd mechanism in what passes for my brain has decided that bringing me to consciousness is a good idea, even when I don't really need to be conscious, as it gives me more time to think about all the stuff you need to think about a couple of weeks before show-time. (That's a lot of stuff, by the way, in case you were wondering.)
I'm afraid there's not much I can do about this. Fortunately the days are so packed there isn't time to be tired, so it's not exactly a problem in strictly practical terms. Also there's a sort of solution awaiting. As soon as the show's over I'll find myself falling asleep anywhere at any time - and I'm very much looking forward to that.
