I have to sleep with the tv on too...I've tried numerous times without it and it just can't be done. I sleep like a freaking baby with it on but as soon as someone turns it off, I can't sleep for the life of me. The sound doesn't need to be up, I just like knowing it's there. Maybe it makes me feel like I'm not alone if I can hear Peter Griffin or Spongebob as I drift off to sleep lol
