Count me in as someone who has never slept for .1s on a plane. Makes for some very long overseas journeys. I think the longest I have been without sleep is 30 hours.
I am flying to England at the end of May and am thankful we leave at 1:30 in the afternoon and arrive at 9:30 pm our time. Way better than overnight. It will be morning in London and I know I won't sleep until that night. Once I am somewhere with light and activity I can't sleep. I will take it easy and definitely try and at least rest. British telly-yipee!
I am afraid to take any kind of sleeping/motion sickness pill as I never do and so am very sensitive to them. I would rather arrive tired than feeling stoned!
So I don't have any tips I'm afraid. I take alot of reading material and earplugs-I hate the osounds people make-throat clearing etc. but that is another story.
Have fun. One always forgets about the flight part when remembering a fun trip!
You think you're not ever going to be able to eat another thing, but alas, you will find yourself feeling strangely peckish around teatime. The more you eat, the more you want. That's the way it goes."
