Just half-and-half, no sugar. Flavored coffee - OK, as long as it is coffee-flavored!! The other ones are too sweet. And no artificial creamers, please.
Love iced coffee in the summer.
Tea, I like to have milk in it. When I had a house and garden, I grew lemon thyme, that way I could have lemon-flavored tea and still put milk in it without the milk curdling.
