here's a semi-helpful nytimes article about outwitting jetlag - with mostly common-sense advice, but oh well. i knew someone who traveled internationally with a rock 'n' roll band for a while, and his strategy was to gradually ease himself into the other zone a week or two prior to departure by gradually staying up later (or going to bed earlier - are you big in japan, or huge in the ukraine?) in an effort to be ready upon arrival... that's not gonna save you from that 12-hour cramped ride in coach, though.
do you have any personal techniques for fighting jetlag? i'd love to know!
