I am not a doctor or psychologist or anything so please take everything below with a grain of salt

I was like you in my 20s, I could drink a lot of caffeine without any effects at all. I was diagnosed with ADHD around 28. At the time my doctor told me that my high caffeine intake was maybe an unconscious way of trying to wrangle with my ADHD, because the treatment for that is stimulants.

Once I started my meds, even a low dose, I basically didn't want coffee anymore. It made a huge difference in my life

Not trying to diagnose you with anything, I just always like to tell heavy coffee drinkers my story in case it might help them if they're feeling like something is off

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?

		Actually I’ve been inattentive as a kid and when I like something time stops I can have really deep focus. But I’ve learn to dig subjects I don’t like to succeed at school and at work so idk if I have ADHD. Sometimes I really hate what I have to do at work and it can be really painful to engage with it and I procrastinate a lot. But I guess many people are like that

		I was an above average school and uni student, yeah. 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)
