The unhappy - what is the difference between the happy and the unhappy? Only this. The unhappy cannot sleep. The sorrow, care, anxiety, the worry that he has, at once take sleep from him. Why do people take to alcoholic drinks, and drugs of all sorts? Only for this. When a man has drunk alcohol because of the intensity of the stimulant, a light sleep comes upon him. His feet, his hands are asleep, his tongue is asleep. He cannot speak plainly. He cannot walk straight, and falls down. The joy of this sleep is so great that when he has drunk once, he wants to drink again. A thousand times he decides that he will not drink, but he does.
