I wake up a 4 am. It happens, I've accepted that every morning, some time between 4:01 am and 4:15 am, my body temperature will rise, my eyes will fly open, and I will wake up.
I will be wide awake.
With little chance of falling asleep.
The best thing to do during these waking moments is to address the overwhelming urge to pee. The timing works out well, so why not?
Still, waking up at 4:00 am every morning is a bit annoying.
Except when it's not.
Like when I'm on the East Coast. 7:00 isn't so bad.
