My brain kept wondering whether the alarm would go off.
Similar stuff has happened to me (not with sunrise alarms, though -- never tried one). The solution is setting a loud, reliable, ‘back-up’ alarm at the latest time at which you could possibly get up in time.
I've also discovered an alternate solution: try challenging yourself to wake up before the alarm goes off. Works even better if you tricked yourself into thinking the alarm was ever actually turned on.
This is the public group instrumental rationality diary for Christmas week. It's a place to record and chat about it if you have done, or are actively doing, things like:
Or anything else interesting which you want to share, so that other people can think about it, and perhaps be inspired to take action themselves. Try to include enough details so that everyone can use each other's experiences to learn about what tends to work out, and what doesn't tend to work out.
Thanks to everyone who contributes, and I hope everyone is having a nice holiday!
