Still good that we have the medicine available that we have right now. Born in a different time and ADHD wouldn't even be considered a real thing.
Hang in there and sometimes just let your brain do whatever it wants :) Constantly forcing and fighting things can get you stuck in a stress spiral.
That, and meditation also helps with being more aware of what your brain is doing
Up until the post-WWII era desk jobs were pretty rare. You'd be in a factory or a farm, or something else not-desk-related.
Anecdata: I did a working holiday in Australia and worked on a farm. No issues with ADHD or other focuses -- exercise, sunlight, no caffeine, and not-desk-related work kept me on task. I notice a big difference even now with carbs and sleep patterns, and how they effect my focus.
Genetically we're still cavemen, and are equipped to always be swatting mosquitoes and looking out for bears, not sitting still and thinking through abstract bit-shifting.
Most drugs need at least two weeks to start having any effect - and the drugs that are shorter-acting (AMP-family mostly) still have a “breaking-in” period before they have the desired effect.
Idk why I'm writing this. I guess it was just on my mind and felt like joining in the discussion.
