How can i stop my addiction to video games?

You do not have a serious addiction. I saw a guy with 68 days 21 hours and about 30 million cod points and very few of those from wager matches. Don't fight the urge!!! It is summer time, just relax and play CoD Black Ops all you want. You are only 13. Try to play a little less when MW3 comes out because then school will be back in.
