MACDUFF: What three things does drink especially provoke?

PORTER: Marry, sir, nose-painting, sleep, and urine.
Lechery, sir, it provokes, and unprovokes;
it provokes the desire, but it takes away the performance:
therefore, much drink may be said
to be an equivocator with lechery:
it makes him, and it mars him;
it sets him on, and it takes him off;
it persuades him, and disheartens him;
makes him stand to, and not stand to;
in conclusion, equivocates him in a sleep,
and, giving him the lie, leaves him.
