Set a quit date. If you are using medications like varenicline or bupropion, these will need to be started at least one week before your quit date. Generally, people have better success quiting cold turkey than they do with cutting back the number of cigarettes smoked daily... so your quit date should be the day you stop completely. Share your quit date with friends, family, and coworkers. Peer pressure and encouragement from them may be very helpful both before and after you quit.
Change your typical smoking behaviors. This means avoiding places or situations where you most often smoke or may be tempted to smoke. This may also mean avoiding spending time with other people who smoke, especially soon after your quit date. Start exercising. This can help reduce stress and prevent weight gain that sometimes accompanies smoking cessation. Keep gum, carrot sticks, sunflower seeds, or other healthy snacks in your pocket or purse. These may help when you feel cravings for cigarettes.
