Mised - You are so right....the problem for me was.....I didn't find out I was one of those who didn't deal with it that well until I made the move from short haul to long haul (and moved my family out to the sandpit). I'm now committed here on (realistically) a ten year money making project and have to try and adapt. Not helped when the company rotate you to Melbourne followed by Rio....Tokyo then LAX etc...or when the in flight rest is way too noisy.
Got one of the mask / noise / light reduction sleep aids mentioned earlier in this thread....does exactly what it says on the tin. Also use Melatonnin but only when I really can't sleep. You can slowly become too reliant on it if over used.
