Smoking one cigarette a day is not considered a successful quit. Successful quitting starts with stopping smoking until there are no physical or psychological symptoms of quitting, which can be called a successful quit. 1. Physical: In the early stages of quitting smoking, you may experience physical symptoms such as thirst, coughing, headache, lack of concentration, tremor, and may also experience painful sleep disruption. Withdrawal symptoms after quitting smoking vary in age and duration, and the physical discomfort will disappear only after quitting smoking successfully. 2. Psychologically: In the early stages of quitting smoking, there are often bad feelings of irritability, nervousness and restlessness, and the temper will become more irritable, which will return to normal after quitting smoking successfully. After quitting smoking, you will no longer be psychologically dependent on cigarettes, and you will be able to remain calm when you see others smoking. Smoking is harmful to the body and it is recommended to quit as soon as possible. If you find the process of quitting difficult, you can go to a smoking cessation clinic in a regular hospital and quit under the guidance of a doctor.
