Oh that is a sadness for sure. I love my Diet Coke and would be way sad if it was changed. We were in Europe and they have Coke Light which tastes awful to me. I didn't have any for two weeks. My first sip was on the plane on the way home with good old regular Diet coke. Have you tried Coke Zero? It seems less sweet to me. I don't love it but it will do in a pinch.
