What is it called when I got enough sleep? [closed]
You could say "I am well-rested".
If you want to refer to last night, you could also say "I had a good night's sleep" to indicate the amount of sleep you got was sufficient to plentyful.
You can simply say that you had a good (night's) sleep:
a night in which one sleeps well.
Did you have a good night's sleep? I need a good night's sleep to be at my best in the morning.
