Decaf coffee. Just regular cocoa. Decaf tea.

Water, seltzer water, lemonade, soda, milk

I like to add a couple drops of flavored extract to my iced water. I prefer orange and mint

Herbal teas usually fit the bill there. Coffee and cocoa both have caffeine naturally, so the only replacements there are the ones where the caffeine has been specifically removed by chemical processing.

Teecino. It doesn't taste like coffee, but it has a lot of the flavor notes of coffee (fruity, slightly bitter, chocolatey, etc.). It also comes in a bunch of different flavors.
