I enjoy coffee, tea and soda. However - my body seems to have a really high tolerance for caffeine, and I dont usually have much of them during the day. So I enjoy the taste of all 3, but don't get the caffeine boost some people do.

A friend of mine has the opposite situation - she can't have any caffeine after noon or she will be up all night.

Anyways...I enjoy consuming all 4. I suppose my vice is tasty liquids.
