Quitting smoking is one of the most daunting challenges you may face in your life. It is an addiction that is both physical and psychological. However, quitting smoking can be done. In fact, you will join the company of millions of Americans who are former smokers.

There are certainly plenty of reasons to quit when you consider smoking's link to lung cancer, emphysema, and heart disease. Smoking also has harmful effects on your family, like exposing your family members to dangerous second-hand smoke. By being a smoker, you may also increase the chances that your children will become smokers.

You have seen the warnings. You have received the advice. You have listened to your kids nag you about it. You know you should quit smoking, but where do you start? Knowing what you are up against can help you form a successful plan to quit.

The Mind and Body Connection

Smoking is addictive—both physically and psychologically. The physical addiction can be traced to the nicotine in each cigarette. It hooks you just as completely as other drugs. The withdrawal symptoms—cravings, anxiety, nausea, depression, and lightheadedness—are similar.

Nicotine surges through the bloodstream and gives smokers a high—a quick jolt that makes them think they feel better. What really happens is that smokers develop a tolerance for nicotine, which is why they increase from one pack a day to two packs a day.

The psychological addiction is, in its own way, just as bad. Smoking becomes second nature, like blinking or breathing. If you consider that one pack of cigarettes can turn into 150 to 200 puffs a day, seven days a week, 52 weeks a year, you will see how hard it is to de-program yourself.

How to Do It

Keep these points in mind when you quit:

You may want to talk with your doctor about medicines that are available to help with smoking cessation. One example is varenicline (Chantix). It helps by blocking the pleasant effects that nicotine causes on the brain.

In addition to varenicline, there are a range of other medicines available to help you quit smoking. Examples include nicotine replacement products; which may be in the form of chewing gum, lozenge, nasal spray, or patches; and an antidepressant called bupropion.

Based on the research available so far, it appears that varenicline works better than placebo and bupropion. However, taking varenicline has been associated with some side effects. The most frequently reported include nausea, headache, insomnia, and unusual dreams. Varenicline and bupropion may also increase the risk of serious mood and behavior changes.

While medicines may be a good option for you, these are definitely not a magic cure. You still need to be very committed to quitting.

For the best results, work with your doctor. Together, you can test your lung function and compare the results to those of a non-smoking person. The results can be given to you as your lung age. Finding out your lung age may help you to stop smoking.

Your doctor can also talk with you about your options, such as:

Trying a combination of these options may work best for you. For example, using a nicotine patch and going to group therapy may help you to become smoke-free.
