What works for me is to get as much sunshine upon arrival as possible. I try to be outside (even if it's cloudy). I then try to stay up as late as possible. Again, next morning, get outside. I've read that sunlight helps to reset your internal clock.

I sleep on the plane as much as possible. You might even want to try to skip dinner on the plane (but bring something to eat if you wake up in the middle of the night hungry). And speaking of hungry, I often wake up the first few days in the middle of the night, wide awake and starving. I try to have something healthy to eat when that happens. Taking alleve (a muscle relaxant) or benedryl might help you sleep on the plane without getting too groggy. I meditate and even if I don't sleep, I am relaxed enough to be rested.

Generally, for me, going west is easier because it is easier to stay up later than to get up earlier. That's why Europe from the US is harder for me than Japan from the US.
