First you’ll need to resist the urge to snooze. No matter where you are going, no matter what time you get there, stay up until midnight local time. Try to get into your normal routine as soon as possible. Get up when you usually do, and try to eat your meals, exercise, and go to bed at your regular times.

Also remember to drink plenty of bottled water. You’ll want to do this to make sure you don’t get kidney stones which result from dehydration and are common among pilots and frequent fliers. Also, for the first day, don’t eat anything with heavy sauces or anything that your body is going to have to work extra-hard to digest. Fruit, raw vegetables, and salads are all good choices.
