Didn't even try to sleep on the flight to Tokyo. The flight landed on time in Tokyo - good thing as I only had a little over an hour scheduled between flights. I spent my 45 minutes running around the airport - added my frequent flyer number to my ticket and checked out duty free. The flight to Bangkok was a little rough, but I managed to grab a couple hours sleep. We actually landed in Bangkok a little early. I caught a taxi from the airport - it felt good to be clued in enough to tell the driver how to get to the guest house I wanted. At the guest house much to my surprise there was one bed left. So by one o'clock nearly 22 hours after leaving San Francisco I laid down to go to sleep.
