At least on the eastbound flights I can set my watch to the destination time zone and fake myself into sleeping a normal cycle. Coming back is like permanent twilight (or noon) and messes with me. I think I may have gotten 3o minutes of sleep coming back.
Those days are _weird_.
When I first was traveling from my place in Germany to a site in California, I had a day where I started at 1a or something, and arrived at my hotel at 6p, while gaining 9 time zones.
And, with the plane, I left at 10a or so, and arrived at 2 or 3p. So it's a really trippy 33-hour day, where I'd spent 25+ hours traveling in a single day, most of it being daylight.
Since realizing that the company only pays for 12 hours of travel a day (you're supposed to stop traveling, after that, I guess), I shifted to getting a hotel at the airport, rather than attempting to travel day-of.
It's especially a good idea, because there is no possible way to arrive and _not_ be tired, while winding up driving for a couple of hours in LA-area traffic at the end of the journey.
