Not really sure on what to suggest for Jet lag per se, but as a point of interest I thnk it's important to note that, when trying to combat having jet lag, it's better for you to not skip sleep or force yourself to stay up. Sleep is like a time bank, and when you deprive yourself of sleep you are, in metaphorical essence, going to have to repay the debt... which is then only making your jet lag worse. Alot of people actually mistaken small amounts of sleep deprivation (I'll just stay up 30+ hours straight and sleep that night and be fine!) for a bad case of jet lag, when in reality your jet lag would be easier to handle by sleeping when your body demands it, and making the time change gradually over several nights.
