I used to live in Asia, and travel back to the US quarterly. Of course, now I live in the US and travel back to Asia quarterly. ;-)<p>What I've found that works for me is to "throw off" my sleep schedule the night before a trip; I sleep for 3-4 hours (usually catching an 8AM flight), then while on the trans-pacific leg, I sleep / eat / read / game every couple of hours.<p>Whenever I "switch" to a new part of the rotation, I get up for a walk around the cabin. I end up getting a few hours of sleep in power naps, watching a couple of movies or reading a decent chunk of a book, or taking care of some work.<p>When I land, I go find a source of caffeine, and then fall back into the "regular" meal schedule for wherever. Dinner at 7 or 8-ish, and I make sure to eat an actual breakfast. Finally, I take melatonin for one or two nights, and then try to sleep naturally.
