I drink almost exclusively carbonated, unflavored water. People *gasp* and tell me all sorts of things that are wrong with it.....but there are people drinking liters of SODA a day and that is way worse than bubbly water.
We bought a soda stream for home, a soda stream for work and every restaurant on main street knows we drink soda water. Even Crossbone likes it -- he knows it's tingly and bubbly and will raise his lips before drinking it. It's hilarious (we don't force him to drink soda water exclusively tho - only when he demands we share
) But it has REALLY upped my water intake!
