I think I may have found a solution to the soda dilemma. At king Soopers the Kroger brand of seltzer water is pretty good. It's lemon lime flavored and all it has in it is seltzer water and natural flavoring. It's in cans which is even better, and Zero calories. Give it a try. It's located on the water isle. Oh and it's cheap too. Only $3 for a 12 pack.
