>A 500ml Diet Coke (assuming you don't mean the caffeine free version) also contains about 65 mg of caffeine, which is the same as an espresso.

that's for one shot of espresso, and most standard regularly-sized espresso drinks are served with two shots, so that's closer to 100-130 mg of caffeine

i've experimented with reducing caffeine and it's overall been a great experiment. but also i take a stimulant for adhd so you could imagine it's easy for me to overdose on caffeine while i already have other uppers in my system. when medicated, a coke zero is basically the perfect amount of caffeine for me if i need a pep without becoming a nervous wreck
