Here are some suggestions:

• Track your progress, and plan monthly celebrations to mark each month you have quit.
• Start a money jar with the money you save from not smoking and invest for a rainy day, buy yourself a gift or go for a nice dinner.
• Get your car detailed. The clean car smell will be a refreshing treat as your sense of smell returns.
• Schedule a monthly manicure or pedicure as a treat, and as a constant reminder that you are tobacco-free.
• Get a massage.
• Go for a refreshing walk in your favourite park.
• Plan a trip someplace you've never been.
• Buy new running shoes or exercise equipment.
• Watch one of your favourite comedies.
• Schedule a dental cleaning right after your quit date.
• Sign up for a class to learn to do something you’ve always had an interest in, such as learning a new language, playing the guitar, or taking dance lessons.
