Why do you have your phone configured in a way which notifications can wake you at night? The only time I see notifications between 2100-0700 is if I actively look at my phone.
If I'm out at night I want to see if my friends text me. Fixed hours for silent notification are stupid and only work for people that don't have a social life.
In the early days of Android there was an app which was able to set my phone to silent based on nearly unlimited inputs, like location, time, app notification, weather, etc. The relevant API was patched out with Android 5 or so, one of the most stupid decisions ever.
