As one who jaunts to Asia on a fairly regular basis I have a few suggestions for jet lag.
3 days before your trip (no more, no less), begin with a kind of fast. Stop eating at the first morning and wait until breakfast, east coast time, the next day to start eating again. If you must eat; no sugars, little if any carbs, especially no breads. If you must eat, have a rasher of bacon and a bit of cheese.
On this second day, go to bed at your regular time but wake up 3 hours early. Yes, this will mean the family moping around the house for hours before you get on about your business (kids going to school...etc...). On this second day, eat your meals on Eastern Time and eat pancakes with fruit, sugar, and syrup. Or whatever, eat carbs. Eat simple carbs like confections and pastries. But only eat regular meals and eat them along eastern time schedule.
Now your on the third day of this. Go to bed at your normal bed time but wake up on eastern time on the day of the trip. On the day of the trip, continue to eat along eastern time schedule but balance your calories with fatty proteins and complex carbs.
You will not have any jet lag. I promise.
Here's what's happening (if you care). Your body's sleep schedule is a biological clock. Your clock gets set by your environment and everyone assumes that to mean light/dark sunshine type things. The number one thing that sets your sleep schedule is your diet. Fasting lets the mainspring on this clock run out. It's mostly simple carbs that impact your circadian rhythm, I would guess it has something to do with insulin levels or other hormone responses ... but I'm not a doctor.
There's research you can read about diet affecting sleep schedules if you like, I'm not a total nutter (yet). I flew back and forth from Detroit to Japan and Korea enough to have fully tested this regimen out.
Also, and not for the kids so much, if you can't work through this 3 day plan get paralytic drunk your first night there or back. You will have a hangover but it will fade in due course and you won't have much if any jet lag. Not sure why this part works, but excessive liqueur intake is my first line of defence whenever there is a problem and it payed off for this one.
