Good question (probably worth its own thread), but I think everyone handles Jetlag differently. This trip was short (just one full day visiting and shopping, and one full day stuck at Sister in Laws's through a storm) that I didn't really get onto a US timezone. However, I applied my own "personal" style ...
Westbound - late night, early morning BEFORE the flight means that by lunchtime takeoff from Heathrow I'm already a bit worn; a can or two of beer (I know - using that alchohol drug
) helps me sleep, though I can even be asleep before takeoff sometimes. Hour or two's sleep and the films, reading, relaxing. This time, I had a good charge in the laptop and I was working. Coffees before arrival in the USA and I can usually keep going well into the evening so that my night will be early, but not unseemly-early. I probably wake during the night, and I'm probably a bit tired the following afternoon, but that's about the sum total effect.
Eastbound - no preparations ahead and again a couple of beers and a good sleep. I find Eastbound much harder if I haven't slept well - and the three terrors here are (a) child kicking from behind (b) Full recliner from ahead and (c) Elbows from left and right (with a special mention for staff who run over protruding feet with the duty free trolley!). Following day can feel a bit long; we landed at 8 this morning and it's now 6 - I'll be in bed by 8 and up again by 4, then doing a full day's work.
Up again early on Wednesday ... out again by 06:00 for the next trip.
More jetlag tips anyone?
