Anyway, I was woken up by the explosions the night before starting work. Maybe it was a bit of jet lag combined with a few worries, but I ended up having no sleep whatsoever that night. It was extremely annoying and continually frustrating. I watched the night turn into day and decided the time had come to take my first sick day -- the kind of thing I really hate doing, I always think I won't be believed. After telling Web that I wouldn't be coming to work I finally managed to have a sleep for a few hours in the morning. Watching a boring film helped surprisingly well.
My body clock seems to have adapted now, thankfully. I feel a new sense of sympathy for people with insomnia.
