@bswpb I wonder if you have any recent studies on carbonated beverages. I also used to think they were bad, but I have heard from many experts lately that data now shows that is false and carbonated beverages are fine as long as they don't contain excess phosphorus, like colas. It's the phosphorus that prevents calcium absorption and not the carbonation. Just putting this out there because there are already so many things we have to avoid, that if you enjoy bubbly water as I do, there seems to be no reason to deny yourself that.
