Fwiw. I've done 1m plus miles in 6 years touching every continent except south america
If flying business class, stay on home schedule till destination. Go to bed lights out at normal time. Wake up and once indestination stay up till normal home time or as late as possible then go to bed.
E.g. leave at 4pm. Stay up ti 10pm home time. Ssleep with whatever personal aid works for you. Noise reduction head phones are mine (plus lots of booze) wake up. Land at 9pm and stay up till i am completely wasted and go to bed. Next day onnto normal schedule.
Interesting. I have the opposite approach. I try to adjust to destination time as quickly as possible. Seems to work well enough for me.
