From the Little Red Book: The alcoholic must learn to "let go" whenever he becomes upset; when over-activity brings him feelings of mental and physical exhaustion; when he becomes extremely impatient; when he experiences anger; when he is bored; when he is resentful. Relaxation will restore his sense of well-being and allow better concentration of his mental faculties which are necessary for an understanding of God sufficient to effect our recovery from alcoholism.
