Always iced, splash of milk (sometimes black), caffeinated af, and never sweetened. Never had hot coffee in my life, iced is better for you anyway. Decaf, cream, and any sweeteners are for silly little schoolgirls.

Depends. In the afternoon and evening definitely decaf (for the taste), other than that obviously with caffeine

Never tried decaff before.

Caffeinated and Black.

I usually can't tell a difference, but I rarely drink decaf. If I don't want to be up for hours I don't drink coffee at all because even decaf has a good bit of caffeine.
