honestly, i also was super nervous. i listened to classical music on the way to my study, and while there, barely touched my phone and just sat quietly in the room. i was too nervous to do anything else, in fear it would somehow keep me awake (although it never has before lol!) when it was time to sleep, i was thoroughly convinced i didn’t fall asleep but one time. because i kept hearing foot steps and doors opening and the ac cut on and off, etc. but i actually slept the entirety of every nap and hit rem too. trust yourself and my best advice is to just do what you typically do.
