I find that playing Guitar Hero or Tetris work wonders =D
Although I do prefer Guitar Hero.
It gets me angry at the game rather than at myself and it's so addictive, you just want to spend ages trying to get better.
I remember having really bad urges and no one was in, so I put on Guitar Hero and spent hours and hours playing it, first on Medium, then going on Hard and now I kick arse =D
Next, Expert ;]
