Health Tip: Signs of Nicotine Withdrawal

(HealthDay News) — Nicotine typically is as addictive as heroin, says the University of California San Francisco.

Within minutes of smoking, the brain releases chemicals that give users a rush. Smokers then get hooked on this pleasant feeling. And when people stop smoking, withdrawal side effects commonly appear.

The school mentions these signs of nicotine withdrawal:

1. Anxiety or depression.

2. Cravings.

3. Difficulty concentrating.

4. Impaired performance.

5. Increased appetite and weight gain.

6. Irritability, frustration and anger.

7. Restlessness and impatience.

8. Sleep disturbances, such as insomnia or sleeping too much.
