after traveling to London (from Boston) every third sunday night for two and half years (arriving heathrow at ~6am, shower at airport and arrive at work for first meeting), I still could not handle meetings after 3pm (London) on monday -- tuesdays I was right as rain, but i needed a nap at 3pm if I had to be active that night. The flights home were much easier -- arrive thursday evening, dinner and go to sleep. rules: don't drink on flights you need to sleep, eat before you get on the plane (eating on the flight is a waste of time) melatonin is your friend.
