-I simply set an alarm on my phone for whatever time I need to get up the next day.

-For me it's winter, so I leave the window only slightly open and put on thermals.
-I lay my DJ next to my bed open to a new page with a pen lying on it.
-I Make sure that bright lights for chargers and computers are covered.
-I Lie in bed staying as still as I can and eventually I fall asleep.
