Last night I picked up a half-smoked cigarette in the street and walked along twirling it in my fingers, trying to think where I could get a light. Then I threw the butt into the bushes. It was a triumph.

This is my life: I feel triumphant when I don’t bring home cigarette butts I’ve found by the curb. I feel triumphant every time I drive a car without smoking. I am no longer a person. I am a nonsmoker. Every ounce of my energy — physical, intellectual, emotional, spiritual — is devoted to not smoking. My thoughts all lead to the fact that I can’t smoke. People talk to me, and their words become little cigarettes in my head. I can’t concentrate long enough to study or even to make a pot of coffee. So I dance around, pick up dog hair, sing, check my e-mail.
