That's one and a half cups of espresso. Insane amounts of caffeine, borderline lethal.
TIL a double espresso is deadly
Usually caffeine poisoning symptoms start at about 500mg, but borderline lethal is in the ballpark of several grams in couple hours. Basically every known case of caffeine poisoning is from pure caffeine or caffeine pills etc.
I was making a joke.
Two double espresso would put you at somewhere between 400mg and 800mg of caffeine. Half of Italy would just be living in a hospital full time.
Caffeine poisoning starting at 500mg is the same as alcohol poisoning starting when you feel nauseated.

10,000 grams of pure caffeine
Because you can’t overthink if your heart stops.
energy drink: 100g caffeie, 400g water. enough energy for the rest of your life :D
Lethal dose's around the 1gm mark, with 320mg being safest daily dose for an adult human. >500mg will likely put you in a hospital, though.

According to your link, toxic dose is >10g/day and not 1g
Also, >500mg/day will not send you to the hospital...sincerely me, drinking 3-4 double espresso (that's ~150mg/cup) before lunch at work. Healthy? No doubt it isn't...but also very far from lethal.
Ah sorry, 2am commenting moment
