“If you can’t beat it, join it” – this method works particularly well when you’re traveling west to east.

This is how it works – just pretend that you’re still in the time zone that you came from (for example Pacific time).  Then just stay up until 2:00 am or later every night once you get home.  That way, you’re really going to bed around 11:00ish Oregon time, a reasonable
bed time.  Then sleep in until 10:00 or 11:00 and you get all the joys of living on the East Coast without ever have to lose West Coast time.  It works great!

(The only potentially fatal flaw to this plan is if you live in a city neighborhood in which parking is ridiculously hard, if not impossible, to find at 2:00 in the morning.  In that case, you’ll probably have to park in a metered spot, which means you’ll have to get up at 7:45 to go move your car to avoid getting a ticket.  When that happens, get up, move your car, eat breakfast, do some stuff, and then take a three-hour nap.  It works almost as well.)

One final piece of advice: this method will fall apart when school starts.
