Mario Kart & Sleep

I'm addicted to Mario Kart and I'm not getting enough sleep because of it. Can you believe I'm trading sleep for video game victories. My victories these days should be getting Maria to sleep at a decent hour and getting myself into bed at a decent hour but no I must be a sadist. I wake up at 4am and I'm at work by 6am but most mornings I don't even know how I got there. I have a problem and I need an intervention and so does my husband, but he won't admit it. Help someone, please break down the door and take away our mini steering wheels. Not only do I have highway hypnosis in the real world but I have it in the video game world.
