>When do sushi rolls usually fall asleep?
Wake up early and sleep early.
Waking up early is fantastic, enabling you to be productive, finish what was left behind or just idle about.
Sleeping early on the other hand is the opposite, even if not troublesome most of the time; well, one thing is troublesome and that is somnolence! Specially because it is not perfectly consistent, it attacks as early as 21:00 or as late midnight, drowsiness is very uncooperative.
>falling asleep as the first rays of dawn start peeking in through your blinds
I can't do it, gotta have total darkness, tape over lights on electronics, everything. I used to work nights and had to totally block and insulate my windows to get any sleep.
I work during the day now and wake at 4 on weekdays so I'm not rushed and 6 on weekends so I can sleep in (for me anyway) and still get up early enough to exercise without encroaching on my day or run errands before people get out.
I work the graveyard shift (00-08AM).
I handle it well until ~6:30AM when I start getting a bit tired, sometimes sleepy in case I'm performing easy tasks.
It is easy for me to fall asleep at 9AM, waking up later at 4PM.
It felt weird at the begining, but got used to it in a couple weeks. Honestly, until I graduate and get another job, would not switch to another shift.
You need to take time off work before you burn yourself out.
You can concentrate your workload and have no personal time, that's fine, but it must be balanced out with time completely off work. e.g. 4 days on, 3 days off; or 2 weeks on, 1 week off; that sort of thing. You have to negotiate this with your boss.
Sleep is for the weak!
