Main thing to notice and focus on are the 2 graphs, and then develop some consciousness about your own oscillations and hill climbs.
In my case, my chosen vice is the computer game Civilization 6, but the principle feels the same. It's an easy source of readily accessible pleasure, that scratches a certain itch, and which I can enjoy even when I feel tired and irritable. I've intermittently given it up for periods of time, with mixed results.
I am curious what others' experience has been?

What I struggle with is the lack of a good hobby to occupy my hands for longer stretches of time while my mind wanders.
Now consider the brain and the mind that doesn't shutdown even when you go to sleep and are supposedly physically resting. Applying the same process used for muscles is necessary. The term used if you don't do that isn't "mind injury" though, it is burn out and corresponding mental health issues("brain injury" is reserved to mean something else).
You need a way to "rest", whatever that means for you. If it's a game of Civ, then great. Reading a good book, extra great. Unfortunately while TV used to be a source of entertainment, I don't believe it is serving that purpose anymore. Why give up Civ if you enjoy it? Limit the time if you think you have better things you'd like to do.
For me, I've incorporated rest and downtime into my life after experiencing what happens when you don't. Having said that, it is still a battle some days if I'm not mindful because we're so used to being "productive" every waking second and actively discourage resting.
I also strongly encourage you try some meditation. It is very simple to do but not easy.
