ELI5: why do stimulatants "fix" ADHD?

Was diagnosed young, and again when I was 21, have been taking Adderall 20mg for years, and thought i was managing the symptoms well, until I spoke with the psych again. They ADDED 5mg and I am already feeling waaaaay slower and clear. How does something that is supposed to speed/"wake" you up, slow a person down?

For those with true adhd, hyperactivity is the body’s attempt to stimulate itself and to stay stimulated. So when you give someone with adhd stimulants, the body no longer has to move to stay stimulated, the meds do it. It’s why when people who don’t have adhd take stimulants they are highly energetic.
