Give you a clear idea of what you must do to gain weight: 1. Quit or try to restrain SY (once every half a month or once a month);
2. Quit smoking or quitting smoking (more than one pack every half month);
3. Go online less, go out for a walk more, and spend more time with friends (this can also restrain sy) to keep your mood comfortable;
4. Shift the goal and focus on other sports or other things. This is how I restrained my heart and slowly focused on my studies (I used to like dota, World of Warcraft);
5. Eat more on time and have a good routine (stomach trouble is a problem for many people, including me).
6. Learn to adjust yourself. You work in three shifts, and adjustment is the most important thing.
Wait, there are many things you can sum up through practice. You are still young, you can adjust, or you will regret it when you are old. Nowadays, many middle-aged people have ruined their health just to make money. Many of them have gone to see a doctor ... These are what I saw during my internship in the hospital, and I feel very sorry ... The most important thing in people's life is "living". Take care of their brothers! ! ! ! !
