Public service announcement that there's a lethal dose for everything, even air and water

Normal cup of coffee (8floz) = ~94mg caffeine

(1) espresso shot (1floz) = ~64mg of caffeine

I think we can just stop there since holy shit, but:

Venti Starbucks cup (20floz) filled with espresso shots = 1,280 mg of caffiene

That's a lot, but not even close to the lethal dose of ~10g, apparently. Actually surprised at how high it is cuz yeah, I've had almost as much caffeine before by acciden and it feels like you're gonna die. I even saw someone who had exactly the same amount of caffiene (4 of the 4-seeving sized monster energy drinks you used to be able to get, 1,280 as well) go from standing to flat on the ground without warning. People thought shed straight up died

Tolerance goes crazy like that

Yeah, same. And I don't even have a preferred taste - I almost always buy different coffee and alternate randomly between preparation methods (or even just the grind with the same method and same grains).

I guess I just like the process itself, not as a ritual or habit, but a simple and totally different task to what I'm doing at the time.

Yeah, same, perhaps more of a 'calm me down' than 'sleepy' reaction in my case, but usually it just reveals that once calm I could/should in fact sleep some more.
