What to Know Before You Quit
When someone smokes, nicotine is delivered very quickly to the brain.
Nicotine withdrawal includes physiological symptoms like headaches, grouchiness, or difficulty sleeping. It also includes emotional and mental reactions ranging from sadness and stress, to happiness and relief.
Withdrawal symptoms begin about 6 hours after quitting. They peak about a week later. Then, the body adjusts to the absence of nicotine, and withdrawal symptoms decrease. It usually takes 2-4 weeks for nicotine withdrawal symptoms to disappear completely, but it can take longer. Withdrawal symptoms are signs that the body & brain are recovering.
Nicotine cravings are different from withdrawal. Withdrawal symptoms go away after 2-4 weeks. But nicotine cravings can last a lot longer. In fact, they can continue long after the withdrawal phase has passed.
Dealing with Nicotine Cravings and Withdrawal Symptoms
Everyone experiences nicotine withdrawal differently. Some people who quit experience really strong cravings for nicotine. Others have hardly any cravings.
