I have the same problem when I fly to south east asia or when I fly back from the US to germany. During the flight I go to sleep straight after dinner and usually I sleep for about 7 hours (ok, it's with the help of some light medication), but when I arrive I have no jetlag at all.

The flight back to the US will be much worse. You start in the morning, then fly for 8 to 12 hours and you arrive in the US in the early afternoon ... unfortunately for your body it's already time to go to bed, but you have to keep up for at least a couple of hours
