Yes, one of the biggest issues on overseas flights is if you arrive at 7:00 am and people want to take a nap. You're better off just staying up all day and going to bed at a reasonable hour. You'll awake the next morning and be ready to go.Really, it's fun to talk about excessive drinking as a coping mechanism, but in this case it's probably counterproductive. Take your motion sickness pills and try to have a positive attitude going in - hey it's my first flight, let's experience it!. If it's a red-eye you're going to be jet lagged anyway and the hangover is not going to help. Best advise is try try try to stay awake at least until 9 o'clock the day you arrive.
