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:
-
Anxiety or depression.
-
Cravings.
-
Difficulty concentrating.
-
Impaired performance.
-
Increased appetite and weight gain.
-
Irritability, frustration and anger.
-
Restlessness and impatience.
-
Sleep disturbances, such as insomnia or sleeping too much.
