Inspired by the other thread of how long does it take you to office, Anyone of you here belongs to the 5 a.m. club (or earlier)?

I had been waking up at 5 every morning since last week, it had been great. I had so much extra time to prepare myself to work. I also manage to read as there are no distractions from group chats, emails.

However, I feel very tired at night and go to bed by 11pm, Used to be 1am 
On the other hand, I won't waste time on dramas and reddit at night anymore 

Hopefully I can continue with this habit.

What do you do if you have the habit of waking up earlier?
