Sleep

I'm feeling sleep deprived. I have had been waking up at 4am recently for no apparent reason. Perhaps it's due to all the stuff going on at the moment, perhaps it's because I do nothing but sit at my desk all day and get no exercise. Perhaps I'm drinking too much or eating the wrong things. Perhaps I need a holiday (we have booked a holiday this week but that's not for another 128 days - but I'm counting)!
