Fish Bro is trying to gradually adjust his biological clock.
He used to go to bed around 3 or 4 AM and wake up around 11 AM.
Last night he went to bed around 10 PM, but woke up at 5:30 AM today and couldn't fall back asleep.
Then he got up to wash up.
This isn't working!
Ideally, he should go to bed around midnight and wake up around 8 or 9 AM.
