Depends how much you drink. I realised my mistake after drinking 2 lites of double-strength coffee daily at work for a few months because it was free in my first post graduation job. I have to make a conscious effort to not repeat that.

Fair enough, everything in moderation. Two litres strikes me as truly exceptional. That said, even that amount probably doesn’t have averse long term health effects if you ensure sufficient water and electrolyte uptake to offset its diuretic effect (another very noticeable side-effect is withdrawal but that’s short-term).

That's ~6 can-sized coffees a day.

Split that into 3 in the morning and 3 in the afternoon and it doesn't seem "truly exceptional" to me. Perhaps a tad overindulgent, but I could hit a handful of people with a bread roll from where I'm sitting who would qualify.

Double strength coffee. I was taking three or four times the level that starts causing noticeable anxiety.

No, that is actually a hell of a lot of coffee.
