There are all levels and versions of addiction. Ask yourself why on earth you are doing something that is tied to so many fatal and debilitating diseases. It's very difficult to quit, so quit now before it gets worse. Count yourself lucky and get something else to make you feel good, like regular exercise or playing an instrument or chewing gum. If you stop forever now, your body can recover to a great extent, but the longer you smoke and the more cigarettes you smoke, the more damage will be done and the closer you will be to a cancer diagnosis or heart disease or stroke. It also gradually makes you wrinkled and causes your teeth to yellow. Ask yourself, am I hungry, angry, lonely or tired when I smoke? What should I be doing when I am hungry, angry, lonely or tired that is healthy for me? Then, plan to do those things, pay attention to your feelings, and do them. Stay away from people who smoke or at least stay away from them when they are smoking. Start hanging around people who are health conscious and try to pick up their good habits. Start an aerobic activity. It's hard to run when you smoke a lot. Dont' be a fool. Give it up now.
