I try to drink a cup of tea every morning. Like what coffee is to most people, tea is for me. It's my waker upper, my morning caffeine dose, part of my routine. I know tea isn't exactly known for its high levels of caffeine, but you'd be surprised on how much. Obviously teas such as white tea, herbal tea and roobios all have little to no caffeine in them. But certain green teas, oolongs and black teas have enough caffeine in them to open my eyes a little wider. Also there is a certain type of tea sold at Teavana called maté that contains 100% of the caffeine found in coffee.
