When you eliminate all stimulation your brain becomes afraid of you not giving it back it's addictive neuro chemical which is dopamine. This thing happens to us all - and it's better to avoid all sorts of unnatural dopamine - because it has a bad effect on your brain's health.
I like that you clarify to stay away from "unnatural dopamine." There are plenty of ways to find dopamine naturally, most of them are simple: Exercise, eat healthy, get more sleep, meditate, go hiking, enjoy music, go out in the sun, and one of my favorites - Go have sex.
