Daily sleep duration?

How much sleep do you usually get per day?

As I do this and that,

I stay up until midnight as a baseline, and I fall asleep around 1 or 2 AM.

My wake-up time is set for 7 o'clock, but

I can sleep whenever I want, so it would be nice to sleep a little more.

If I look at my phone for a while and go to sleep past 2 AM, the day feels too tiring.

But if I look at my phone the next day too...

It's past midnight again in no time.

I really need to get enough sleep to take care of my skin and overall condition, but I just can't seem to do it.
