Earlier quoted context omitted.
I just volunteered the same suggestion. I am undiagnosed "inattentive" (but it's as obvious as hell, in retrospect) and I clearly self-medicate with caffeine; I used to have an awful coca-cola problem and now in my fifties I like to take a bit of care over my coffee.
Yep, inattentive here too It goes undiagnosed because we aren't hyperactive problem kids in classrooms, and if we're lucky enough to be interested in the subjects we can excel in school If you're anything like me you've been called lazy a lot in your life when really you're just too bored by stuff to engage with it?
I tended not to get "lazy" too much because I guess I found a way to be interested (my father was good at pointing me to the fascinating bits of homework etc.). Though looking at my school reports in retrospect it is clear that I did much worse at things I did not care about, and if I think about times I was shouted at for doing a poor job, disinterest was why.
I do, however, fall down intellectual rabbit holes a lot because I need to be interested to get stuff done.
I am now in my fifties and the biggest problem is that I have fully burned out — very severely — because I endured such high levels of stress (caused by trying to freelance while having ADHD), that I ultimately became deadline-dependent to organise myself.
I've spent two years recovering and in that process I have learned that much of the typical advice (cut out caffeine) is wrong for me. Indeed cutting out caffeine left me depressed and eating worse. It is sugar I have to manage, which seems like an overoptimisation (I am quite skinny at times and I can forget to eat)
