Many studies have shown that the time spent playing video games drive mad has a direct effect on the risk of addiction. So limiting gaming is the first step in balancing the benefits and harms of gaming.
For game addicts, you should not stop playing suddenly. You need to give yourself time to adapt. Instead of stopping playing the game suddenly, gradually reduce the amount of time you spend on it during the day. You can set your own time rules to play the game and take it seriously. Time gradually decreases until you feel like you can control your gaming.
