Starting with a day off may help some suffering from jet lag! From a sleep disorder site:
"There is no specific treatment for jet lag, but trying to adapt to the new time zone as soon as possible may help. For instance, some travelers may benefit from the psychological effect of resetting their watches to the new time zone as soon as they depart. Most people try to minimize the impact of crossing time zones by planning their activities to accommodate the effects of jet lag.
"One useful strategy for easier eastbound travel is to take a daytime flight. If a traveler flies eastward by several time zones during the day, they may arrive at their destination in the middle of the afternoon, home time, and in the middle of the evening, local time. For example, if they leave Boston at 10 a.m. on a flight to London, England, they will arrive in London at 9:30 p.m., GMT. However, their body clock tells them it's only 4:30 EST. They should try to go to sleep at a normal time in the new time zone. If a traveler needs to take an evening eastbound flight, they will arrive in the middle of the night, home time. In this case, immediate rest helps. They should try to sleep for a few hours when they arrive and then try to stay up until bedtime. For most people, westward travel is easier to adapt to than eastward travel. This is probably because it is generally easier to elongate one's day by staying up later, than to try to shorten one's day by going to sleep earlier."
