If you can't help yourself, then the iPhone's "Do Not Disturb" feature, or Android App, will be your new best friend. You simply set the time span, it could be from 9 p.m. until 6 a.m., and all calls and alerts will be silenced during that period. If you are expecting an important call, then you can set it to allow calls from "Favorites" or repeated calls if they call more than once in a three-minute window.
