New idea.
A game has ~45 achievements. Go to your local convenience store and buy 45 Mars bars (substitute for a different chocolate if you're weird and don't like Mars).
Tell a hobo to sit outside one of your windows.
Every time you get an achievement, throw one of the Mars bars out of the window to be eaten by the hobo.
When you've finished with the game, eat the rest of the Mars bars.
You'll put on a hell of a lot of weight, and it'll cost no small amount to buy 45 Mars bars for every game, but you can't put a price on curing addiction.
Thank me when it works and you are addicted to Mars bars now.
