> But if you're a long-time caffeine consumer your baseline (no caffeine alertness) goes down, and in the long run coffee just brings you up to the same level non-consumers have for free

Citation? It sounds a lot like that's something that you find convenient to believe, perhaps because you gave up coffee and you want to tell yourself you did something good for yourself.

Coffee is essential for my productivity, not for pleasure.

For sure it is (for the reasons I described above). As for pleasure: I don't know, maybe you are the one who hates its smell, and taste, and just takes it as a medecine. It's not impossible, but it would make you an outlier.

Btw, I do consume caffeine, nicotine, and sometimes alcohol. I'm just conscious nothing of those gives me a superpower. Even though they can give a subjective feeling of superpower sometimes.

There was just a study published which proposed to show amphetamines of all kinds, actually decreased productivity, and significantly delayed time-to-resolution of cognitive problem solving tests...it also did show the people on the amphetamines vastly overestimate their productivity "boost" from the drugs. Obviously, devil's in the details.
