With coffee, i usually have it with a teaspoon of sugar in a big mug, but sometimes i add some sweetened condensed instead of sugar. Same for black tea and chrysanthemum. For chamomile and oolong, i have it without adding anything, since i usually take chamomile at night and treat it as a flavored water. For oolong the taste is strong enough as it is.
