I try to adjust to my new time zone a little bit the day before I fly out when going eastbound... On westbound runs, I try to adjust to the local time by sleeping OR forcing myself to stay awake during the flight. A good way to do this is to UNDERSLEEP on purpose before a westbound run - hence you tend to sleep a little on the flight.
An example of this is SFO-TPE depart mid-day or so; some people sleep, I will stay awake as you get into TPE at 7PM or so - hence I want to be tired to sleep normal local time.
Going eastbound I try to get as much sleep (if I land early AM) and try to stay awake as late as possible to sleep normal local time. However if you are one of those people that always wakes and sleeps the same time while at home - you may be up at 4AM anyway... I however don't have a set sleep pattern when at home due to early or late conf calls - so I seem to pick any time to get 7 or 8 hours sleep - even when travelling
