A few years ago I flew on a DC10 from LGW to DFW as SLF. I had an absolute *killer* headache upon arrival and hit the sack at around 9pm local time. (I can't remember which painkillers I took, but I don't usually get any kind of reaction). When I returned home a few weeks later I slept like a baby!
Back in April this year on the same route (this time on a 777) I didn't have any kind of problem. In fact, I hooked up with some friends out there and we were out until gone 2am local time. On my return home I only had an hours nap.
My experience on the 777 seems to be the opposite to most...
