It's 8:23 here, but I was up and running early.
You go to bed at 11pm and get up at 3? No wonder you are tired. That's not enough sleep.
I'd be staggering around here in a mess. Been there and done that before. I got up at 3:30 am and started work at 5. Did that for 17 years. I did love my work though, but the perpetual 'Not enough sleep', takes it tole after awhile.
