It's not unusual for me to wake up in the middle of the night and not know where I am. I take sleep medication to deal with all the flights. But I find it helps to eat at the same time every day.
It's still my happiest time when I'm eating.
My flight time is important to me; I actually prefer a longer flight to a short one. That way I have time to read a book, watch movies, and think about new dishes.
