May live long enough to enjoy retirement, grandchildren, etc. I'd like to stop in a group setting. When I don't smoke, I feel restless, and I can't concentrate. I'd like to use the nicotine gum you recommend, but I'm afraid I'll become addicted to it. Don't diet now - there will be time after you are an established nonsmoker.
Exercise is an effective technique to cope with withdrawal and to avoid weigh gain.
Avoid high-calorie snacks. A small increase in weight may not hurt your appearance. Smoking is unattractive, causing yellow teeth, bad breath, stale clothing odors, and possibly wrinkled skin. I don't have the willpower to stop smoking. More than 3 million Americans stop smoking every year.
