Well, that was quick! I'm back to 4 hours of sleep.
It's kind of funny. My wife got 4 hours of sleep the other night. Throughout the day, she complained so much that things were hard and that she was feeling so tired.
She also went to bed at 8pm.
Throughout the whole time, I was saying to myself, "I have lived with this short sleep for months and months on end. Yeah, I occasionally say I'm tired, but I don't make a big deal about it."
I once thought that maybe I should complain that I was tired—this was many years ago.
The feedback was: go to bed earlier, drink water, and get over it.
So that was the end of trying that
It is interesting how the people closest to me have no regard for anyone's experience other than their own.
