It is normal to have a smoking habit again after half a month of quitting, and you can take countermeasures to reduce the possibility of your relapse, such as physical exercise and eliminating tobacco-related things around you. 1. You can ask your family and friends to supervise you and help you to firmly believe in quitting smoking. Most of the people who relapse into smoking are unable to control their behavior because their willpower is not strong enough. 2. Conduct outdoor aerobic exercise, which can both distract your attention and improve the ability of your lungs, such as jogging and swimming. 3. completely remove tobacco, lighters, ashtrays, and all other smoking-related substances from your home and reduce the number of things you may smoke. 4. Use smoke substitutes, such as lozenges and chewing gum. If discomfort occurs during the process of quitting smoking and is difficult to relieve, it is recommended that you seek medical attention in a timely manner and be actively treated under the guidance of a physician.
