I found several Dr. Ned Hallowell's books helpful, see https://drhallowell.com/read/books-by-ned/ in particular "Delivered from Distraction" and "Answers to Distraction."

The Amen Clinics use PET scans of the brain to differentiate between seven types of ADD: https://www.amenclinics.com/conditions/adhd-add/ You may find these write-ups helpful in refining your understanding. Dr. Amen has a book that I found helpful https://www.amazon.com/Healing-ADD-Revised-Breakthrough-Prog...

I don't take stimulants beyond caffeine, I meditate most days at least once a day, which I find helpful, as well as not stay up too late. I keep a pad of paper by my bed to capture ideas. Working to music seems to help.

If you get a lot of ideas, you should reconcile yourself to only acting on a small fraction of them and worry less about all of the possibilities.

I try to take care to keep the commitments that I make, writing them down and tracking them. And here it is important to keep a close track.

I may be less impaired than you are, although many people have noticed I seem to get a lot of ideas. I collaborated with a partner on a book once, and at one point, about halfway through, he was frustrated with me and said, "You are a geyser of ideas. We don't need more ideas, we need to complete what we set out to do."
