And when I have a craving to do it now?
Wait 15 minutes. Challenge yourself to read a magazine, listen to music, or play your favorite game for 15 minutes. Cravings only last a few minutes!

Do something else. When a craving hits, stop what you’re doing immediately and do something else. Simply changing your routine can help you shake off a craving.
Take deep breaths. Breathe through your craving by inhaling (through your nose) and exhaling (through your mouth). Repeat this 10 time or until you’re feeling more relaxed.
