I realize some of you must have been world travelers with 15+ hours stretch of flight. Now that I am doing this on a frequent basis, perhaps you can share what works for you.

I've done a few tricks myself. No, $$$ business class is not the answer. What I have done so far is to force the body into the destination time zone, thus tricking the circadian rhythm:
- About 12 to 24 hours pre departure, I either sleep or stay awake following the time zone. Booze or energy drink titrate to effect.
- During the flight, I do likewise. Stay disciplined and doze off skipping all the movies, and vice versa. Booze and coffee titrate to effect.
- Finally I change the food intake timing as well. Force myself to eat on the destination breakfast, lunch, and dinner time in the plane and prior to departure.
I found that these combined with exercise following usual time routine at the destination immediately upon arrival (just like acclimatization to weather) tremendously minimize, if not eliminate jet lag. I am fully functional upon landing and not being in a fog. The waking up at 3 and 4 am is the hardest one to overcome.

I imagine when you are deployed across the world and several time zones over, you don't have much luxury of adjustment. So what works other than just gutting it out?
