Well, I definitely didn't know all the ins and outs of making it.  I just stuck the bag in a cup with hot water over it!  I bought the Yogi Teas brand, so I don't know how good it is.  It is only 10 mg of caffeine in a cup.  

Sounds wonderful the way you guys make it.  I don't know why it makes me hurt.  Caffeine has always done this to me...

You could try a cup of White Tea and see if it affects you differently.  If you have a natural food store, they usually sell tea in bulk so you don't have to invest in a whole box.
