Buy a real alarm clock. Set it on the other side of the room.
Turn off your phone before bed. Plug it in somewhere far away from where you sleep.
Don’t turn it on again until you’ve been awake a while, until you’ve finished your first cup of coffee, written your morning pages, meditated–done whatever it is you need to do to steel yourself against the onslaught of nonsense.
Begin your day by grounding yourself in yourself.
