Sleepless in Seattle (well, in London really, but anyway)

Sleeping has been a problem lately for me. Well, not the sleeping bit, but the part where I wake up wayyy too early in the morning. For the last four days I have woken up around 7am with no alarm, this morning I was up at 5.30!That's just not nice. Strangely though, I feel fine today, although I suspect I will be dog tired come 6 o'clock and time to go home...
