I found the recipe now, thanks, can't wait to try it! Lets see- flying to the US we left home at 8a, Dublin airport at 11 and Heathrow at about 3 in the afternoon I think. We got to Chicago late at night, into our hotel about 11 so we just went to bed and it worked out fine.
Coming home we left JFK at 6pm, got to London at 6am and then had to wait around for the flight to Dublin so it was 11 am before we got home. I went to bed in the afternoon for a couple of hours and then got up and proceeded as normal. Went to work the next day and was tired but not too jetlagged. I did sleep on the plane home- I bought a gel sleeping mask in Boots and wore the headphones with the classical music channel and slept for about three hours. The killer for us is always the 2 1/2 hour wait for the connecting flight home. I'm sure you will do just fine! I am very jealous that you are off on your big trip- will miss you when you are away though
