Enroll in an evening class just for fun. This is a good time to indulge yourself with a sense of newness and enjoyment. Suck, bite, or chew. You may miss putting something in your mouth. Avoid fattening foods.
Some people substitute sucking lollipops or candy.
Carrot or celery sticks are good to bite and good for you. Chewing gum is also a good substitute. Others enjoy cinnamon sticks or licorice roots from health food stores. Caffeine is a stimulant like nicotine. Once you stop smoking, your body's chemistry changes and caffeine stays in your body longer.
