And we say, you're not allowed to go to bed until 1am, for example, and then you have to get out of bed at 6am.

And it does work.

So you do that with your psychologist telling you exactly what times and that's the only time you have for sleep.

And so what happens is after the first night where maybe you didn't sleep much at all,

the next night you are really, really sleepy and tired.

And it's really hard to stay awake until midnight or 1am.

But when you actually get into bed, you fall asleep a lot faster.

And it's because it's that biological need for sleep kicks in.

And then you start sleeping a lot more.

So you will sleep for that four or five hours.

Whereas before, you might have been in bed for 10, but only sleeping for five hours.

So in that way, it's resetting your body's ability to fall asleep and stay asleep and starts that association that bed is a place for sleep, not being awake.
