I was reading Wikipedia one day and found out this is how Anthony Hopkins quit smoking. he seems like a smart man so I decided to give it a go. I am so glad I did. explaining it to people is tough- YOU JUST HAVE TO LISTEN FOR YOURSELF. Carr goes over every aspect of smoking and puts it all into perspective. he doesnt stress the health benefits or how much money you save he breaks it down to WHY people smoke and how easy it is to quit. as someone whos tried to walk away numerous time I finally found the easy way out!
