I am a moderate drinker whether on terra firma or aloft. Wine with dinner, perhaps a port or brandy afterwards which is not much different than when at home. An exception will be made if a good scotch is being offered and I might have one on the homeward leg of a long business trip but never on the outbound journey.

Getting plastered on an airplane never made much sense for me. Feeling like crap when you land isn't worth it.
