When I travel back to the States, I find that it's easier for me flying there then when I'm flying back here. I usually go the route of Manchester to Philadelphia, then Philly to Nashville. Usually I get into Philly at about 1pm Eastern time, then around 6pm to Nashville, depending on flight times and delays etc. I feel more awake when I come to the States, probably because for my brain, when the sun is out, I need to be alert and awake. The other reason is excitement cause I'm going back home. Also, before I fly, I set my mobile phone clock to American time, my Nintendo DS to American time and try to set my mind to that time too. It's something I've always done on my numerous flights to home. When I get back here though, it's worse, cause I usually land at about 815am British time, and it takes about a week to re-adjust fully. I also feel depressed cause it's always 2 years between visits. Sorry to go on so long, I was just being descriptive of how it works for me. LOL!!! I do love the days when the sun doesn't go down till around 10 or 11pm here.
