I found out that it's caffeine. I always thought i just naturally wanted to stay up until 2:30am, and then be okay waking at 6am for work.
Turns out that when I drink even a single cup of coffee, it totally fucks up the thing in my brain that tells me I'm tired.
So I started the lengthy process of cutting out all coffee.....and after a week or so...holy shit...I was EXHAUSTED by 9:30pm. Like, I'd fall asleep in my computer chair at like 10:30. My sleep started to regulate. I felt so much better.
Like, you don't realize how much of your brain is operating in this hazy fog...until you've slept properly for a couple weeks. I could concentrate on things, I wasnt so lazy. I WANTED to do more things.
