Firstly, you should limit the time that you spend playing computer games and pay more attention to other things . Secondly , you should get up and go to bed at a specific time so that you can form a habit of getting up and going to bed regularly . Thirdly, you should do exercise for about half an hour every day to strengthen your body . I do hope you can get rid of computer games and form a healthy lifestyle.
