I love nicotine because it helps wake me up if I am getting sleepy during work or while I am driving. But my lungs feel bad sometimes and I cough a lot, especially in the morning! I was reading on this website, nicotine quit, that there is really no harm to the body from nicotine. But all the tars and harmful gases in the tobacco smoke are really the things that are dangerous to my body. This website really reviewed each method commonly used to help people quit smoking very well and helped me to choose the method I am currently using.
