Shakespeare on drinking:

Drink, sir, is a great provoker of three things: 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. 

-from Macbeth, 2.3.21-30

Ah, this is so great.
