Soda

Soda is the one thing I just can't give up. First, I worried about the sugar/HFCS, so I only drink diet. Then sodium, so I prefer to drink Hansen's rootbeer (no sodium). Now I'm worried about the lining in the cans, the carbonation, and just generally setting a terrible example for the kids, given the amount of soda we suck down each day. Water's fine but just not the same, juice has empty calories for the mos part- what other options do I have? I'd like to cut traditional soda out of my diet by the time the boys get old enough to know they want it . . .
