Anything addicted was so hard to stop, but you can try with to do something in business. I also addicted to games, before I can spend 8-10 hours in games everyday, how I stop that, first motivate myself or put something positive in my mindset, "If I keep gaming like these how my future will be?" From 8 hours/day now only 1 hour playing games, actually since I join this forum I more like do something useful for my futures, like participate in bounty, first I try write an article till now maybe 30 minute playing games.
