Seidman, Ph.D. From the back of the box: "Why are you still smoking, even though you want to quit? Based on 20 years of research with countless smokers in his clinics at Columbia University and NY Prebyterian Hospital, Dr. Daniel F. Seidman understands that people smoke--and quit--for different reasons and that what works for one smoker might not work for another." *Are you a Situational Smoker? Monitoring your reactions in different situations is a step toward permanently losing interest in cigarettes. *Are you a Worried-about-Weight smoker? Properly using treatments like Nicotine Replacement Therapy (NRT) can help you quit and get healthy in all aspects of your life. *Are you an Emotion-Triggered Smoker? Scheduling your smoking breaks and sticking to a rigid smoking schedule helps break the link between stressful situations and craving cigarettes. In a comprehensive, 30-day program, Dr. Seidman explains how to take advantage of all the tools at your disposal to end the month smoke-free and feeling stronger than ever!
