Try to create goals for yourself outside of video games. For example, outside of work, I like to play with PCBs and racquetball in my spare time. Be mindful of the urge to go back and play. Try to separate yourself from the area in which you play (for me it's the living room). Playing another game won't really solve the issue. If you feel like you must--as a last resort--delete the game from your console. Or, put away the console altogether. Are there things that you've wanted to do outside of gaming? Start there.
