Besides milk...what other type of drink would mix well with cereal?

A couple minutes ago I had a bowl of cereal with not milk, but coffee in it..and the thought crossed my mind…what else would taste good with my cereal?...I know some of you might think its gross…but its my alternative to milk because I’m lactose intolerant…Sadly…I love milk but not willing to go through the “side affects” so I try to avoid it as much as possible. I really don’t like skim or silk milk…its like eating yogurt and saying its ice cream…no bueno..So any suggestions? Also I prefer it to be something cold…not warm or hot…lol.
