I fly a lot for work, too, and I'm convinced that the worst cause of jet lag is the air travel itself, not the time zone changes. With the craptastic quality of economy class travel these days, the lack of food service on semi-long flights (I'm looking at you, Delta, on your US transcontinental flights!), the insane flight schedules (I'm looking at you, India, for whom all international flights heading west leave somewhere between midnight and 3am!), the ridiculous and time consuming airport security theater (I'm looking at you Sao Paulo immigration zone!), the "everything costs extra" revenue model that forces everyone to try to carry-on everything ... resulting in unnecessarily lengthy boarding processes when a slew of bags end up being valet checked anyway, any nearly every other part of flying. Perhaps I am being too harsh and uppity, but flying commercial airlines these days -- with VERY few exceptions -- feels like riding a city bus, which is decidedly not restful. Sorry, I just had to get that off my chest. I've flown to India, Brazil, Mexico, cross-country US, and everything about it sucked. The only bright spot was Global Entry, which imho is the way immigration & customs should work for everyone (minus the rigmarole of enrolling), and Pre-Check, which is the way check-in security used to be. This rant was just a long-winded way of saying I blame the airlines for a lot of my jet lag problems. The fasting method works well but I get grumpy when my blood sugar drops too low so I generally avoid this. Getting on the destination sleep pattern by forcing myself to stay up until that time zone goes to bed is my usual method, and it generally only takes two days to get completely adjusted. With a wife & little kids at home, though, I'll sometimes make a decision not to adjust so I can minimize the unpleasantness when I return (I live in North Carolina and when I travel to California I always stay on my home timezone, going to bed by 8-9pm and waking up at 3-4am Pacific.).
