Getting addicted to something you know won't last might work. But for the dark side of addiction breaking, you only need to hack/cheat the crap out of the game (infinite everything, flying, indestructibility, mapedit huge structures, etc...), and get bored with it since you've ruined the gameplay :tongue.gif: Of course, this might not work for everybody, but it's a good bet.
1) Play almost non-stop until you burn yourself out or a family member decides to intervene.
2) Replace it with another addiction (one that doesn't damage your health).
3) Question yourself why would you drop Minecraft
Or do what I did:
4) Get Portal 2, beat multiplayer and singleplayer with all but 4 achievements within 12 hours played and return to Minecraft.
Its easy. Just play it more and eventually you will get bored of it. Until the next update comes, anyways. Then, depending on the update and your mod, you will leave it in about 10 minutes, or you will become addicted for a week or so again. repeat until who knows how much.
