Usually, I just smoke cannabis until my body goes “TIMBEEEEERRR!” ;-P
Seriously, though, routine plays a big role. I tend to lay down/wake-up at around the same time every day. About an hour before I go to bed, I put on a comfort TV show & brush my teeth. At this point, notifications are being silenced on my phone until the next morning, so less incentives to pick it up. While I’m watching the show, I intermittently close my eyes for a few minutes as a signal to my brain about the direction we’re heading, helps keep the peanut gallery in my head from getting chatty right as I’m laying down.
White noise while I sleep is required, I need something constant that covers-up the incidental noises. Otherwise, I pop awake when someone runs the faucet or what-have-you.
That’s what I’ve figured out works for me, YMMV.
I’ve been using wayblue on my own desktop. They have sane defaults & very pleasant theme. They do a good job keeping their image up to date & enable auto-updating from the get-go.
