Soon the brain's chemical structure actually changes. It becomes hooked into wanting more and more nicotine to make the effects last. When the brain stops getting the nicotine it's used to, we begin to feel withdrawal cravings--actually the brain craving nicotine.

As this nicotine addiction sets in, the brain links everyday habits with smoking, boosting the role of cigarettes. Normal everyday activities begin to trigger the urge to smoke. Drinking coffee in the morning. Talking on the phone. Work breaks. Driving.

So when you try to quit smoking, you're actually fighting a battle on two fronts: 1) physical--that is, nicotine addiction--and 2) habitual, the activities, moods and events linked with smoking.

Let's start with cravings. Once you stop smoking, that's when your brain really starts screaming for nicotine. Your withdrawal cravings can actually intensify in the days after you quit. That's where Therapeutic Nicotine--like that in Commit--is proven effective. Absorbed through your mouth, the nicotine in Commit reduces your nicotine cravings and relieves some nicotine withdrawal symptoms, without the harmful tar or carbon monoxide found in cigarette smoke.

Commit Lozenges help stop cravings before they start, increasing your chances of success by allowing you to focus your willpower on changing your behavior.

That's where Committed Quitters comes in. Committed Quitters is an online resource that can give you an individualized stop-smoking plan to help change the behaviors that reinforce your habit. Enrolling is easy, and access is free for users of Commit Lozenge. You'll get a multiweek plan tailored to your specific needs, including tips to help you along the way, while Commit's strong medicine helps relieve withdrawal cravings. Commit plus Committed Quitters significantly increases your chance of quitting, even if you've tried before.

Start with the right strength. Commit is the first and only stop-smoking aid that offers you different strengths based on how soon you smoke your first cigarette in the morning--a method leading experts believe is a better measure of nicotine dependence.

Get an individualized stop-smoking plan from Committed Quitters. Your plan can help you overcome your unique barriers to quitting smoking--and increase your chances of success. For example, if you're used to having a cigarette with your morning coffee, you'll get specific advice on overcoming that habit and desire. Look for information in your package of Commit Lozenges, or visit CommittedQuitters.com.

Follow the Commit 12-week plan. Commit helps your body gradually adjust to less nicotine. Over a 12-week period, you will use fewer and fewer lozenges, as shown in the chart. But remember, it's designed for a 12-week course of therapy. And for the first six weeks, use at least nine Commit Lozenges a day.

Worried about weight gain? It's a real concern for many smokers. But it's small compared to the risks of smoking. And when you use the Commit 4 mg Lozenge, it can actually help reduce weight gain while you quit.**

Want more ways to take off those extra pounds? Develop new, healthy habits like eating right and exercising. Have low-calorie, healthy foods handy, chew slowly when you eat, and drink lots of water while you're quitting.

• Do not use more than one lozenge at a time or continuously use one lozenge after another. Doing so may cause hiccups, heartburn, nausea or other side effects.
• Do not use more than five lozenges in six hours, or more than 20 lozenges total per day.
