P. G. Wodehouse,
The Little Warrior
“ Doctors, laying down the law in their usual confident way, tell us that the vitality of the human body is at its lowest at two o’clock in the morning: and that it is then, as a consequence, that the mind is least able to contemplate the present with equanimity, the future with fortitude, and the past without regret. Every thinking man, however, knows that this is not so. The true zero hour, desolate, gloom-ridden, and specter-haunted, occurs immediately before dinner while we are waiting for that cocktail. ”
