Most people have the best success with quitting smoking by setting a quit-smoking date and then stopping on that date. If you've tried that method and it hasn't worked for you, you might want to start the quit-smoking process by gradually cutting back on your smoking. To cut back gradually: 1. Delay your first cigarette of the day. 2. Smoke only half of each cigarette. 3. Buy only one pack of cigarettes at a time. 4. Trade one smoking break a day for physical activity. Build on each success until you've quit smoking entirely.
