8 hours per day, after waking I feel myself broken, sleepy and it’s much hard to concentrate and stay active. So, I decided to check if the other people feel the same as me if they sleep longer than needed and what exactly they feel.

longer than 8 hours per day?
How exactly do

they feel?

worse if they sleep more than 8 hours per

day, than if they sleep less. Also, I think that the most of them feeling sleepy, broken and zoned out after long sleep.
