Stop-smoking products are a legitimate way to handle withdrawal symptoms and tobacco cravings. Some types of nicotine replacement therapy, including patches, gum and lozenges, are available over-the-counter. Nicotine nasal spray and the nicotine inhaler are available by prescription. Prescription medications might be an option, too. Bupropion (Zyban) can help control nicotine cravings. Varenicline (Chantix) can reduce both the pleasurable effects of smoking and nicotine withdrawal symptoms. Talk to your health care provider about what stop-smoking products may be right for you.   Need practical advice on diet and exercise? Want creative solutions for stress and other lifestyle issues?
