Actually I never felt the need to be diagnosed with ADHD. So I just looked up online and at first-read I don’t think I have something particularly different that could classify me but I might be wrong. Pushing it I also read that there is genetic part to cafein sensitivity but my parents don’t drink coffee at all so I guess I’ll never know. It’s not really a problem though, I can drink double espresso and take a nap or go to sleep which is nice. I can enjoy very good specialty coffee without trouble
