Be super anxious that your spouse is going to start belittling you for not getting anything done so that the moment movement anywhere in the house happens you bolt awake and start cleaning something, get a divorce, move to a new house so all the noises are different and everything sets off the “oh fuck I need to wake up and clean” response, then carry that anxiety over to assuming your super caring new roommate is going to secretly hate you unless you’re always awake and cleaning something. Worked for me anyway I can wake up hours earlier than I used to I don’t even need an alarm
