Dexedrine feels like it (1) increased the "volume" on the outside world, so that it could compete with whatever's happening inside my head and (2) increased my ability to choose what I was focusing on.
Contrast with Adderral, which felt like cutting off my peripheral vision (like wearing blinders, or a costume mask), only for my sense of focus and awareness instead of literal vision. (I hated it).
Caffeine "just" ups overall energy levels, so it would give me more energy to direct focus... but it also amped up the things that would generate distractions.
Huberman Lad has a good episode going into the brain structures, which aligned with what I think I've experienced.
But yeah! It's well known (AFAIK) that people with ADD have "opposite reactions", although it's more about the complex engine under the hood.
