On the flight back, try to nap during "night" at your destination.

Moderate your booze intake on the flight back, drink as much water as you can (this really does make a difference for me).

When you arrive, try to get outside into some natural light during the day. I find that if I exercise durig the day that I arrive, it makes me feel better and helps me to stay awake longer.

Stay awake as late into the evening as you can stand - I try not to go to bed before 9:00 PM.

By the 2nd or 3rd evening, I am usually well on my way to resyncing timezones.
