I have been sleeping on the couch in front of the TV for about 7 years now, ever since I had my very first experience with horrible insomnia. I remember one night lying in the total dark in the bedroom, feeling "wired" inside, racing thoughts, anxious, unable to sleep. And I could not fall asleep all night long. And it scared me terribly. I'd never had insomnia before.......and lying in bed hour after miserable hour in the total darkness was a nightmare all its own.
Ever since then, I have to have the TV on. Lying in total darkness in a bedroom makes my insomnia worse. I know it's not really healthy as a sleeping pattern, but it is the way I've learned to fall asleep now. I also get up 1-3 times a night to pee......sigh. I wonder what a full night of sleep would feel like.
