Smoking is harmful to health, so it is best not to smoke. Make up your mind never to smoke again from this moment on. An hour has passed. Forget it. Let's have one. Tobacco is a drug from a certain angle, and it is better to describe not taking drugs than taking drugs. In the absence of cigarettes, can't you stand loneliness and often can't stand temptation? Since you used to smoke more than one pack of cigarettes a day, it was a chronic suicide mode of more than 20 cigarettes. Now you only need three cigarettes a day, which is a good thing. It is best to give up slowly. As for whether you will gain weight, it is related to your diet and living environment. If you eat too much, you will be free, sleep, wake up and eat carefree, then you will be fat. But busy work, running up and down, people who use their brains too much will lose weight. Pay attention to your health, exercise more, eat healthily, don't smoke and drink less, and combine work and rest.
