I don't know what it is about travel that so wipes me out, but whenever I spend more than about 90 minutes on airplanes in a given day I wind up totally flat. It's worse going west than it is going east, but right now it's 10 after 9PM and I feel completely and totally exhausted. This after getting a reasonably good night's sleep yesterday and spending the vast majority of today either driving or sitting down someplace boring.
Tomorrow morning I go back to work and find out whether or not I get to move to an office closer to the rest of my research group. On that note I'm off to bed.
