Jumping on this conversation a bit: I was recently diagnosed and am still very much in the "what helps?" and "what parts of my personality/habits are connected to this and which aren't?" stage. Do either of you by any chance know a healthy online space to discuss this with others?

I would recommend avoiding any subreddit related to ADHD.

I honestly would try to stick to materials written by mental health professionals and possibly talking to a therapist (your company might have an EAP that can help with this) over interacting with any online community I'm aware of on this matter.

I find online mental health communities tend to be "if I have a hammer, everything is a nail," and aren't open to other explanations for any traits or struggles. They also tend to suck in the people who aren't doing better with treatment, while the people who found systems that work for them leave for greener pastures. On the opposite side there are communities that are anti-psychiatry and refuse to consider medical treatments. In general these spaces tend to be very black and white.

I do like the Astral Codex Ten open threads as a space that's relatively neutral on the topic, though they lean very biohacker in a way that gets ahead of the science.

I found Finally Focused by James Greenblatt to be quite helpful. He makes sure key minerals and vitamins are in a good range before prescribing stimulants.

This sometimes solves the problem by itself, or it reduces the levels of stimulants needed.
