Chew the Nicorette gum slowly until the taste becomes strong. When the taste is strong, rest the gum between your mouth's jaw and cheek. The nicotine is absorbed by your mouth's lining. After the taste has faded, resume chewing the gum until the taste becomes strong again. Keep repeating this process for about 30 minutes. To help manage nicotine cravings and withdrawal symptoms, you can also chew a piece of gum whenever you feel the urge to smoke. Over time, you may find that you need to use fewer and fewer gums to control your cravings.
