My alternative view (and not to be taken from a health perspective) is as follows:-
Firstly, you are in the holiday mood.
Secondly, I cannot bear long flights.
So I consume as much red wine as they will let me ... and fall into a blissful sleep (coma?).
Mind you, you wake up with a wooden neck, swollen ankles, a bad (and yet tolerant) mood <under the circumstances>

and a gob that would flatten a herd of cows, let alone the Immigration Officer that hastily waves you through the signing in routines on arrival.
It works perfectly ... apart from the arrival ordeal ... but I guarantee that you will not have a hangover in the morning ... you will be up at 0400 (local time) as bright as a daisy ... and ready to start on the Rum Punches by 1000
Have a great holiday.
