It was only really after I got to university last year that I started really drinking coffee and taking it seriously. These days I drink at least 4 cups a day, usually in the morning or mid-morning before lectures. I have it strong, black and with a tiny amount of sugar. Also, it has to be properly ground coffee, made in a cafetiere or coffee machine. I won't touch instant any more.
Of course, as a Brit, I'm legally obligated to drink tea at least once a day, so I do that as well. Tea leaves, of course, with one sugar, sometimes milk. Depends on the tea.
