Mental health symptoms may flare up when you first stop smoking, but there are many things you can do to increase your chances of a successful quit. It is important to have your symptoms under control and work closely with your doctor when you quit smoking. Your medications may need adjusting, and counseling support may be needed. Although many people feel that smoking relieves stress and improves mood, it has been shown that after the initial withdrawal symptoms, cessation is usually associated with improvements in depression, anxiety, stress and psychological quality of life. Discuss quitting with your doctor, counselor or psychiatrist before you start. It is important to plan your quit and consider quit medications to alleviate withdrawal symptoms.
