get enough sleep
have a good sleep

So much for an early night and a good sleep.

Very likely a good sleep will make all the difference.

He got his first good sleep, six and a half hours, on Monday night.

So getting enough good sleep is not a problem for everyone who works nights.

So I just want a good sleep, and perhaps it will all be better in the morning.

Start by getting at least eight hours of good sleep a night.

In fact, I'm not even going to talk to you until you've had a good long sleep.

Not far to go now and you can have a good sleep.

No more to do now but get a good sleep.

I haven't had a good sleep since we left the station.
