How much sleep do you need to function?

My needs are not germane.

The reality is that I only get 2-3 hours per night.

I can function a few days on 4 hours.

5 7 no more, no less.

8 hours

4

8

I sleep more than you...08 hours

Around 5 or 6

5 to 8

6-8.

To function 5 or 6 to can get me by. To feel good the next day? About 10.
