Cut straw the same length as a cigarette. Use it in place of cigarette. You can go thru motions of lighting, inhaling, knocking the ashes off, and even stub it out all without actually smoking it. It is the habit of these motions that are hardest to break. The nicotine cravings are gone in about a week. If you are earnest about not going into stores to buy more, you can't light up. If you must shop before kicking the habit, only buy food and take with you the exact amount of money necessary for food. Leave the store without buying more tobacco products. That is the toughest test yet when you know you don't have more cigarettes. When you can go to the tobacco counter to buy other items, not wanting cigarettes, then you know you have become a non-smoker.
