- No, under no circumstances.
Show answer and explanation
Correct answer: Yes; when the quality of sleep was not good.
Yes. How well you've slept matters too. Interrupted or shallow sleep doesn't restore you, even if you get plenty of hours, and leaves you drowsy the next day. This can happen at any time, not just when you've slept during the day to drive at night.
