No jet-lag and lots of work

Two things I have found about traveling to Europe: (1) I start working early, but then with the US office coming alive midday, I tend to work into the late evening. Last night was no exception as I was online until almost 11pm dealing with work stuff. (2) If I do manage to stay up until at least 11 the first night without sleeping during the day, usually my clock resets without jet-lag. Sure enough, I crashed a bit after 11 and slept like a rock until almost 9am! Fresh as a rose, after walking around for fresh air and breakfast, I got back to my computer a couple of hours ago...
