Bit of a side story, but I should've known I had ADHD when my brother was diagnosed and our (obviously undiagnosed boomer) parents were the kind of people that'd drink coffee after 6 pm and sleep just fine a few hours later. And while I enjoy caffeine I've dialed it down a lot as I really don't see the same benefits as when I was younger, and also feel like I'm just wasting money on coffee beans the price of which have risen almost 50% since covid-19 began.
