What sparkling water is loaded with sugar?? I just checked the label for the ones we had been getting, Kiwi Blue Sparkling Water Lemon, and it has no calories/sugar. It's literally just "Carbonated Spring Water, Food Acid (330), Flavour."
Oh, I thought you were referring to lemonade. I never really buy the stuff so didn't know there was non-sugary lemon fizzy drink.
