surprised at the numbers of business people on here admitting to drinking whilst flying. Very early in my exporting career I realised that jet lag was far worse if you drank alcohol, the real issue being dehydration. So I used to drink a lot of water, refuse the junk food and sleep through the flights to arrive in decent nick.
I would have guessed that the flight drink problem was confined to holiday travelers on the likes of Sleezyjet not business types in club.
