I found Diet Root Beer. That stuff is good, and I can't tell it's diet, like diet everything else. I am also very into the ICE sparkling beverages. It has that carbonation bite that I miss in Coke without all the "diet" taste.
By the way, it has been so long since I have been fully engaged on Spark, I forgot we are knitter sisters! I love the Rosebud cardigan. The back is beautiful. Are you on Ravelry? Have I asked that before?
