I quit 5 years ago. It was not as difficult as were my other attempts. I used my recommendations. But that was not all the story. A lot of people had used doctors recommendations and failed. I had used the same medications and failed earlier but I found a method. And voila, it worked like a charm. You've got to learn this method. For every cigarette you smoke, it reduces your life by 11 minutes. Thus each carton represents one day and a half of lost life. Every year you smoke a pack a day, you shorten your life by 2 months or 4 months if you are two packs a day smoker
