The urge to smoke will soon go away, whether you smoke or not. Distract yourself by focusing on something else.
List situations which trigger you to light up a cigarette—and try to avoid those situations.
If you know other people who smoke, ask them not to smoke around you.
Keep track of how much you spend on cigarettes. Put your daily cigarette money into a savings account and use it to buy a reward for yourself after your first smoke-free year.
You will likely have withdrawal symptoms, because nicotine is addicting. Symptoms may include nervousness, irritability, temporary depression, dry mouth, cough. Remember that these withdrawal symptoms are temporary, and will go away in a few weeks.
Take it one day at a time. If you slip, you are not a failure. If you smoke today, tell yourself you will quit again tomorrow.
Studies show the more often you try to quit, the more likely you are to quit permanently. Using two methods at once also increases your likelihood of success. For example, you may want to join a smoking cessation class, and use nicotine gum or the nicotine patch at the same time.
