I have too much stress in my life to quit right now. Maybe another time would be better. But remember that you, like all other people, will always be under some kind of stress. Waiting to be stress-free before trying to quit smoking may just be an excuse for not facing your nicotine addiction. I can't quit smoking because I'll gain weight, and that's bad for my health, too.
Some people actually lose weight.
If they do gain weight, most people gain only 5 to 10 pounds, which is much less of a health risk than smoking. Exercise and eating low-fat foods can help you keep from gaining too much weight. Switch to a brand of cigarettes with a lower nicotine content while smoking the same number of cigarettes every day. Cut out a few of your favorite cigarettes during the day. For three to five days, use a notebook to keep track of when you smoke each cigarette, and what you're doing and how you're feeling when you reach for a cigarette.
