If one drink makes you more comfortable with your flight and you lose your inhibitions and fears with JUST ONE DRINK, then obviously you don't drink very often, if ever. (My limit is 3 drinks, before I need to stop. It used to be 2 but I recently increased it, due to my glass of wine in the afternoons, since retiring.)
As the very clever poem goes, "you had some of the best times You'll never remember with me Alcohol." I think that's a song, too bad the quoter wrote Anonymous instead.
