It worked for me. When I started engaging into more intense physical activities and going to gym, I was literally disgusted by cigarettes. I was feeling that awful, heavy smoke going into my lungs and messing with my circulatory system, so I drastically reduced them. In less than 2 weeks I quit altogether. Working out helped me as it cleansed my body. Getting rid of cigarettes afterwards came as a natural process. I'm curious if you guys share a similar opinion.
