Invented this concoction tonight at work. Too far from the sink to stop and rinse the Crystal lite sunrise out of the bottom of my glass (little powder left over from mixing in the glass - about 1/8 tsp). I poured in my chocolate RTD and a can of Canfield's Diet Chocolate soda over ice and it was FAB FAB FAB.
Can't wait to get home and try in the blender where it will be really smooth.
