A tip for short trips:

If you have to take a short trip (like a business trip) and you can do it, stay on your own home time zone. It takes about a day per hour difference to adjust, so if you travel from east coast US to west coast for a 4 day trip, you would be heading home just after finally adjusting to the time change. I have gone to the west coast for 4 day trips and just got up at 6am instead of 9am and went to bed at 9-10pm instead of 12-1am. Went home and did not miss a beat.
