Query: It takes an idiot to know one

This book is interesting, and I bought it while trying desperatley to quit while I was pregnant. It focuses way too much on available treatment methods (the patch, drugs, etc.) and not enough on practical gradual cessation. I wanted to know exactly what benefits my body was getting for being smoke-free for an hour, a day, a month, etc., because anyone who's quit knows how unbelievably horrible you feel, especially the first week, and what prevented my quitting in the past was not seeing some immediate benefits such as greater oxygen or at least better endurance during exercise. I haven't smoked in 5 years, and I'm glad I quit, but I'm still not understanding how it benefitted me beyond the typical exagerated and questionable research into the likelihood of obtaining certain diseases. A better book is the no nag guide.
