It depends for me. I usually sleep with a tv or my laptop on or something. I hate sleeping in silence. But the Beau loves it. So when I am with him it takes me longer but it's usually around 30 minutes. Although when falling asleep with the tv on there is always that chance you will end up watching the end of the show... and then get drawn into the next... and then 4 hours later you are cursing yourself...
