Drinking alone is enormously self-protective, at least in theory. The solitude relieves you of human contact, which can feel burdensome to even the most gregarious alcoholic, and the alcohol relieves you of your own thoughts, of the dark pressure of your own company. Drinking alone is what you do when you can’t stand the feeling of living in your own skin. Boswell describes this in his Life of Johnson: “I drink alone,” Johnson explains, “to get rid of myself, to send myself away. Wine makes a man better pleased with himself.”
