That's right. No more Diet Coke, Diet Pepsi, Diet Dr Pepper, or Coke Zero (all of my favs). They have a hidden gluten: CARAMEL COLOR. I have wondered why I felt so sick after drinking a Diet Coke. Now I know why. No more for me. Seriously a sad day. :( I will have to become a fan of Sierra Mist, Diet 7-Up and Diet Sprite. Yay?
