Jet lag and secondary jet lag

I handle jet lag well upon arrival in the US. We function during the day, despite waking up at 3 am for several days. By the second morning the kids already woke at 7:30. The return is different. Typically we are all awake at night the first week, then I suffer for an additional week. It's not just the jetlag; it's having to jump back into the summer "routine." I find myself not remembering things that happened during that first week at home. And my husband complains about "secondary jet lag" from everyone else's night-wakings.

We arrived yesterday afternoon. My 7yo then slept all night, getting up in time for my husband to take him to camp. Go figure. My 4yo slept for a while then lay quietly with her head on my lap during the wee hours, and then slept again from 4am to 1:00 PM. I slept only from 6:30 to 10:30 am.

I am determined to beat the jet lag this time. I have to order school books, prepare sheva brachot, and plan a vacation, while keeping the house running with everyone home all day. I read that when fatigue hits, one should drink coffee and take a nap until the caffeine kicks in. I plan to try this approach, but am open to other suggestions.
