tl;dr - get yourself on the destination time clock as soon as you're in flight. When you land, eat and sleep like the locals instead of hiding under the covers for a week.

"When traveling east it can take about one day to adjust to each hour of time difference."

That's crap. I've hopped my entire family (including small kids) over the Atlantic multiple times and it's never taken more than a day or two to adjust. Just power through the sleepy phases until you get a second wind.
