The urge to smoke may last about ten minutes, but it will pass. Whether you smoke or not, it passes. If it's safe to do so, scream or yell to let your feelings out. In the first few weeks after quitting or cutting back, you might feel strong urges to smoke. Although cravings are worse right after quitting, they can also come later.
Cravings are often worse in times of stress.
They can also be very strong if something happens that makes you really want to smoke. Remember the craving should only last a short while. Cravings may be worse if you are a heavily addicted smoker. Talk with your doctor. Although not for everyone, it may be right for you to use a nicotine replacement.
