This flushes the nicotine and other chemicals out of your system faster. It can help keep your mouth busy.
Take a deep breath break instead of a smoke break. Take a few deep breaths. Hold the last one. Breathe out slowly.
By delaying or holding off, you are calling the shots. Your craving for a cigarette will probably pass in a few minutes. Just wait it out, the craving will pass.
