Flying west is great. The flights east are brutal.
I'm an early riser and I always hated flying West. At 4:30am (local time) I was up and ready to go before anyone else in the office was even thinking about getting up. And since I didn't usually have keys or a way to get into the office my morning was wasted waiting on everyone else to arrive. Flying East is easy (for me). :)
I used to travel from London to the Bay Area for work with some regulatity. The first few days were amazing, because the combination of westwards jet lag plus night owl meant that I was getting to the office nice and early every day. As the jet lag went away, and I started to acclimate to the timezone, it usually took me less than a week to be back to a night owl routine, even without the usual stimuli.
