I was able to get a prescription just from a family doctor: no referral needed. In fact, it was my first appointment with them since I had moved a few years ago and hadn't needed a doctor since. They went through a questionnaire about how frequently I experienced certain manifestations of symptoms in regular interactions with people, and the score was enough for them to move forward with medication.

From what I have seen, it is typically a much more involved process. If it matters, the prescription was for Straterra, which is not a controlled substance, so that might have meant we needed to go through fewer hoops. My doctor seemed willing to try other medications though. I also went to a smaller practice rather than a big hospital, so maybe that makes it easier to advance things.

I chose to get evaluated in the exact same process as you, even first thinking about the idea after seeing a lot of relatable neurodivergent memes. Over a couple months, I made a list of odd behaviors I seemed to do unusually frequently, and what prompted them. I realized it was very likely more than just unrelated personality quirks that were disrupting my life and making it harder for me to do basic things that others seemed to not struggle with. I also had a decent amount of my list be best explained by autism, but honestly I was more scared of that label and didn't bring it up with my doctor. I wanted to see if ADHD treatment would help with the others first.

So far, the benefit I've had with Straterra has been pretty minor compared to the side effects, but I saw other people saying it took time to adapt to it, and anyway I can try others too. My doctor originally recommended it because it was working for some of her other patients. I'm going to probably finish the supply I have and try something else.

Anyway, that's my ADHD diagnosis story so far. I can answer questions if you think of any.
