Funny post, I have own experience to spend more than 30 shots in one single day.
But after this day my body was told to me "no more coffee" about 3 days.

BTW. I don't have any coffee addiction, and can live without coffee lot of days even month.

But I like coffee, and like to brew good coffee for good people.
Also some latte-art allure me and I was make a few post with my trying in art:)
