This could not more perfectly reflect my experience had I written it myself. I was diagnosed with (also quite severe) ADHD recently, and it seems it was a surprise to literally no one but me. A solid third of the people I've discussed it with had assumed I knew and just wasn't well treated.

Even though it's number 1, I do want to emphasize it for those who are reluctant. Finding an effective medication has been one of the most net-positive personal changes I've ever experienced. And if it isn't for you, there's no harm is simply stopping :)

Edit: I should have kept reading, Mo3 sums up my contribution here much better lol
