Leave early enough so you can rest after you arrive. Then use this time to rest, instead of party. Ask your travel agent, car rental company, or host for a list of the main radio stations at your destination. Ask the hotel for recommendations on restaurants that provide reliable delivery service. Include time for exercise or walks.
Many hotels have exercise rooms.
Start slowly if their equipment is different from what you are used to. Even a brief phone call means a lot to them. Eat the same foods, sleep on the same schedule, and get exercise. The air is much dryer in the plane that on the ground. Also, avoid alcoholic beverages because they dry you out.
