Depends on the meds, but Adderall is a combination of different amphetamines and dextroamphetamines. Some of which are added just to make it uncomfortable if you take too much.

The greatly simplified idea is that people with adhd have trouble using parts of their brain at the time they need to. So by increasing all brain activity the parts that are normally diminished are about normal. The side effect is that all the rest of the parts are amped up.

This isn't quite right. Adderall is a 3:1 mixture of dextroamphetamine and levoamphetamine. These are different enantiomers (configurations) of the amphetamine molecule. The two molecules have subtly different effects in the body, but as far as I know, neither is added to "make it uncomfortable if you take too much".

Fair enough. A doctor basically explained it to me like that over a decade ago, and I took their word for it. Which is uncharacteristic of me to just take someone's word for something, and repeat it.
