Annoyance toward adhd'ers

I am curious if anyone has noticed themselves getting more or less annoyed with others who have adhd when they themselves are medication vs not.

I was officially diagnosed with adhd this year (36 y/o) though my teachers and doctors had told my parents since I was very young that I had it. My dad recently told me that he'd wished he'd followed through on their recommendations and helped me when I was young as he has seen such improvements in my life, mood, etc.

My dad also recently just had to move in with me. In the few weeks he's been living in my home, I have never been more convinced on anything in my life that he also has adhd. At his age though, he refuses to see a doctor about or get any treatment.

I've noticed that when I'm on Vyvanse, I find more of his adhd habits annoying. When I'm not on Vyvanse, they don't bother me. Maybe because they're so similar to my own? Vyvanse has been life-changing for me, my life, my marriage, etc. in so many ways and I am thankful for it. But I find myself more annoyed with my Dad when I'm on it vs not.

Anyone else have an opinion on this?
