The Wine of Forgetfulness

In Wong Kar Wai's odd martial arts film, Ashes of Time, a character finds a cask of wine that will make the drinker forget.  As he consumes the wine, his memories fade away, until he suddenly gets up and rides  away toward the dawn.

 I can tell it will be a night without much sleep and no rest.  A quick Google brought me to Proverbs 31:7,"let them drink and forget their poverty and remember their misery no more."
