Carry something to put in your mouth instead of a cigarette, such as a mint-flavored toothpick or some carrot sticks. On a walk, take deep breaths and focus on how good the fresh air feels in your lungs. To ride out a craving, you could also sip ice-cold water, take deep breaths, keep your hands busy by squeezing a rubber ball or doing a crossword puzzle, or meditating.
