>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.
