Ten past eleven, the episode has finished, and you are still sitting there. These bedtime affirmations are for that stretch: the twenty minutes between meaning to go to bed and actually being in it.
What bedtime affirmations are for
Getting you up the stairs, roughly. Not producing sleep. The research on relaxation techniques for sleep is thin, and guidelines treat them as a modest option rather than a treatment. What a line can do is close a decision you'd otherwise keep reopening, and keep the last half hour from becoming the part of the day where you plan everything.
The moment you decide to go up
The credits are rolling, the sofa is warm, and standing up is the entire task.

Standing up is the hard part. The rest is just walking.

The next episode will still be there tomorrow.

I can go up tired instead of waiting to be exhausted.
Why the last half hour decides the night
Researchers have tested this directly. Give people a mentally demanding task shortly before bed and their measured sleep onset stretches out. The body is no less tired. The engine simply hasn't been switched off.
That puts the useful moment earlier than most advice does. By the time you're lying in the dark, the state is largely set, and you are negotiating with something already underway.
The trouble is that this stretch has no trigger. Every other transition in a day comes with one: a door, a meeting, someone waiting. Getting off the sofa comes with nothing except your own decision, taken at the hour when deciding anything is hardest.
So it helps to borrow a trigger from something physical you already do. The hall light. The lock on the front door. The phone going on to charge somewhere other than your bedside table.
Teeth, lights, locking the door
Ten minutes of autopilot, and precisely when tomorrow starts arriving uninvited.

My head can plan tomorrow. It doesn't need me joining in.

Nothing here needs solving before morning.

This is the walking-around part. Nothing is being decided.
Leaving the phone on the other side of the door
The step most people skip, because it has charged by the bed for years and moving it feels theatrical.

Checking once more will not make it smaller.

The reply can be written by a rested version of me.

I am allowed to be unreachable for eight hours.
Lines that order you to relax, and lines that don't
Most bedtime lists are written in the imperative, telling you to be calm. At eleven at night that reads as one more instruction you're failing to follow.
My mind is peaceful and still.
Announces a state you can check against, and probably fail.
My mind can keep going without me steering it.
Lets the noise exist and takes you off duty.
I release all the stress of the day.
Releasing on command is not an available action.
Everything in this house can wait until morning.
A claim about timing, which is checkable.
I am ready for restful, deep sleep.
A prediction about the next eight hours, made by someone who cannot know.
Whatever tonight is, I have stopped for the day.
True regardless of how the night goes.
For the last ten minutes
Lights off, nothing left to do but arrive.

The house can hold whatever is unfinished.

I have stopped for the day, whatever tonight does.

This part of the day belongs to nobody else.
The day is allowed to end before everything does.
A line to return to
What to expect, honestly
Making the last half hour deliberately dull can shorten the gap between lying down and letting go, and it is about the cheapest change available. It cannot make you sleepy, fix a difficult schedule, or treat a sleep disorder. Weeks of lying awake, or waking repeatedly through the night, call for something else entirely. The approach with real evidence behind it is cognitive behavioural therapy for insomnia, and that starts with a doctor rather than with a better evening routine.
