I am not sure if I understood this question but with unmedicated ADHD you really have to write everything down, even the smallest, simplest tasks, and a lot of information for "future me". I even have to write about things that I do every day. Nothing really sticks in your mind. Notetaking is not a choice but a neccesity. When you are medicated you still want to take notes it you want to be even more organized but you can choose not too and probably be fine like a lot of other people without ADHD.

As far as I know I do not have ADHD. I still find it quite useful to write everything down and make sure that I completed everything I needed to do that day. Very easy to forget to reply to someone or that some small thing has a deadline upcoming.

If I really care about the meetings I attended being useful (not often), I will take notes on what is discussed and decided.

I'm not the person you're directing the question to, but I actively have to self medicate so I don't remember every thing.

I also need to take notes to raise the important things above the useless things that I remember.
