Teavana!

I love Teavana teas. They are expensive, but I don't know that they are all that more expensive than other good loose teas. I can buy a canister's worth and it will last me quite a while.

I love their chai/chai blend the best of all. This consists of a blend of White Ayurvedic Chai (their most popular tea) and Samurai Chai Mate. The salesperson talked me into getting German rock sugar, saying it tasted much better than regular sugar in their teas. I have found that Teavana teas taste awesome without sweetener of any kind. Nor do I need milk or lemon or anything else in them. Since plain tea has about 2 calories per cup, I can drink all I want, being mindful of any caffeine content they may have.

I have even bought a little mesh strainer ball, which I carry to work. I carry whatever tea I want in a little plastic container. I can have the convenience of instant tea any time I want a cup. All I have to do is heat up some water, add the tea, wait for it to steep (3 minutes, in most cases), and enjoy!
