After many transatlantic trips to visit family in England, I've developed my own anti-jetlag routine. I'm not a big fan of using drugs for sleeping, so I don't take any -- they put me too soundly asleep for good functioning on arrival. (Ambien instructions suggest that you only use when you know you will have 7 -8 full hours to sleep. JFK to LHR is more like 7 hours total, so that's a problem for me right there, especially if I need to drive right away. If I did decide to try Rx sleep meds, I would test them at home first for a couple of nights, just to see how I reacted. YMMV...). And of course, a seat in Biz or First would be the very best remedy!

1. Select the latest flight possible leaving from, say, JFK. If my bodyclock thinks it is 6 pm my chance of sleep is just about zero. Much better with a 9 pm departure (plus you arrive at a more civilized hour, also.)

2. Arrive at airport and check in early enough to have time to eat supper before takeoff (and keep the supper light and easy to digest).

3. While still on the ground, set my watch to arrival zone time.

4. Once on the plane, assuming I'm in the back of the bus, get as settled as possible, with earplugs and eyemask, blanket, water bottle on hand. BA cheap seats have those headrest wings, so I don't need a pillow. No movie, no in-flight meal (not a huge sacrifice!) Even if I only feel as if I'm dozing and not sleeping, I stay in "sleeping" mode, and usually manage to drop off pretty soundly.

5. On arrival in the UK, freshen up as much as possible (washing face and brushing teeth makes it feel like morning). If time allows, I'll get a good breakfast (in LHR Terminal 4, Caffe Italia on the mezzanine: breakfast is fresh cooked, and coffee is good.)

6. Stay outside as much as my schedule will allow. If it's a sunny day, that's even better. If you MUST nap by the afternoon, set the alarm and only sleep for an hour -- more will just throw you further off track. Get an early night, and by the next day you should be all set.

And to your question about driving to Wiltshire. If you're taking the motorway, you'll find "service areas" with plenty of food and coffee -- cell phone services, too. If you print off a trip planner from the AA website <http://www.theaa.com/> that will show you where the services are.

Have a good flight!
