[correctanswer]

Jane, age 28, has tried to quit smoking several times, but hasn't succeeded. She's now dating someone who is allergic to cigarette smoke, so Jane decided to seek professional help. Her therapist conducted an initial interview to determine the reasons why Jane wants to quit smoking, and to identify the situations that trigger the most intense craving for a cigarette. Then the therapist devised a treatment plan.
At each treatment session, Jane was required to smoke cigarettes two at a time, consuming eight cigarettes in the amount of time she usually spends smoking one or two cigarettes. The sudden rush of nicotine to the brain made Jane dizzy. Her heart began to race, and she felt nauseated.
After five sessions, Jane was finally able to quit smoking. She still feels an occasional craving for a cigarette, but when she picks up the cigarette, she feels sick. So she's able to put the cigarette down and do something else instead.
