The symptoms and feelings that occur after quitting smoking are related to the patient’s smoking age and the size of the addiction, and the exact time varies from person to person. For the average patient, within 1 week is the most uncomfortable time to quit smoking. Most patients who smoke have a 60% relapse rate within 7 days, and some patients may experience a strong withdrawal reaction on the first day due to their long-term dependence on tobacco. After quitting smoking, patients are prone to physical and psychological discomfort such as headache, fatigue, anxiety, impatience, and fidgeting. These uncomfortable symptoms will gradually decrease after 2 weeks of quitting if they can be adhered to; the symptoms will basically disappear after 1 month; and after adhering to it for some more time, patients will have symptoms such as coughing when they smell smoke or smoke again. Therefore, patients need to pay special attention in the 1st week of quitting smoking, and can divert their attention through other means, such as watching TV, eating fruits, drinking water, etc.
