I have become so used to being in the room with the TV on 24/7 too long. I will know when I need to stop sleeping in the living room. It will be when I can't get to sleep because of the TV. BigD has always wanted to leave the TV on in our bedroom all night and it drove me nuts. Just could not go to sleep with it on. I know the reason it doesn't keep me awake now is all the medication I've been taking. As soon as I get completely off the drugs, I'm sure it will drive me nuts again.
