In my experience jetlag affects everyone slightly differently and you can have good and bad trips however well practiced you are. I have a better routine travelling east as I do it more frequently. Travelling out to N/S/Central America always seems weird to me, but I only go that way 3-4 times per year. Being able to get decent sleep if you’re on a plane at the appropriate time also helps.
Travelling east I’d plan to:
1) leave the curtains open to encourage waking up more naturally (only works during the summer in the UK 😉 )
2) desperately avoiding trying to sleep during the day so that you have the maximum chance of sleeping when you actually go to bed
3) trying not to change too much in one go – generally I’ll go to bed 1am or 2am rather than any earlier, to try and maximise the chance of sleeping through when I do nod off
4) Always be wary of the “afternoon nap” sleep – i.e. if you go to bed at a time that could conceivably be an afternoon nap in the place you’ve just left then you’ll be wide awake an hour later and be stuffed for sleeping properly.
Generally, always try and live as far as humanly possible on the destination timezone (whether travelling east or west), albeit I may be going to bed a few hours earlier/later than I might normally. Be very careful if you’ve got to drive/operate machinery when you’re not really wide awake…
