My sure-fire method of getting to sleep on a long-haul flight is to watch an in-flight movie. I drop off very quickly and then I'm frustrated because I still want to know how the film panned out. Book an aisle seat which enables you to get up and move around without disturbing fellow passengers. Wear socks with non-elastic tops. They are often sold as diabetic socks on Amazon or Ebay. If you are liable to get cold feet, carry a pair of slipper-socks in your hand luggage.
Bon Voyage!
