Any one or several of these may work for you. Wrap your cigarettes like a package. When you want a cigarette, unwrap the package and write down what you are doing, how you feel, and how important this cigarette is to you. After two weeks you'll be smoking less and understanding more about why you smoke. If you smoke when you want to relax, try other relaxation methods such as taking a walk, talking to a friend, or reading a good book.
Some smokers turn to food during the quitting process.
On a 3 X 5 card, make a list of what you dislike about smoking and add to it as you discover new ones. Read it daily. Make a short list of special items you want or would like to buy for someone else. Use the money saved from cigarettes to purchase these items. When you crave a cigarette, wait three minutes before giving in to the urge.
