I have a Minecraft addiction, what should I do about it?
Substitute it with something like Gmod.
Oh dear...Doxial, if you have a MineCraft addiction, just keep away from MineCraft. Garry's Mod isn't like MineCraft. In MineCraft, to build things, you need to gather materials. In GMod, it just gives you everything. As Yahtzee said:
That 80-foot-high golden statue wouldn't be so satisfying if it wasn't for the entire continent you had to turn upside-down to find all the ore.
I'm not sure if there is something out there that makes you WORK like MineCraft, so the best would probably be to either stay away from it, or satisfy that addiction. MineCraft is a rather harmless addiction, so I say just play until you get bored. That will solve the problem for you.
