Same here. I have set a schedule been yrs now that between 12a-10a I'm not disturbed by any calls isnpite of me awake by 2-3a daily and have star marked family contacts and only they can interrupt me.I sleep with the phone off. I don't pick up unknown numbers unless I am expecting it. If someone calls in an emergency/the world burns because I don't pickup an unknown number, I am more than happy with it.
