I drink about 8-10 cups of black coffee a day, which is what my brewer makes.

I don’t have any issues with sleep but I don’t feel any sort of boost from it, I just enjoy the way it tastes.

I’m curious how consistent this can be seeing as coffee can be made so differently. I know the coffee I make at home is incredibly weak compared to what you’d get at a cafe. I use about 2-3 tablespoons of freshly ground beans for those 10 cups. Starbucks tastes like they use double that for a cup.

I can’t imagine I consumed that much coffee despite the large number of “cups”.
