A great alternative to the Soy Chai Latte is a Soy Chai Misto, no added sugar beside what the soy has. Chai tea bag, soy and hot water! Also is great with the other teas offered!
Margo- I don't suggest using excedrine to quit caffeine, the asprin in it isn't good for you. Try weening yourself off by getting half decaf, or teas. It may take a while but it will work, I promise! I quit drinking coffee a little over a year ago by that method and let me tell you I was ADDICTED! Working in a coffee shop does that =) But I highly suggest slowly taking caffeine out, because if you just stop you'll get the headaches and that's never fun! Good Luck
