Does anyone know of a decent replacement for Sunkist Diet Lemonade soda (which was taken off the shelves maybe a decade ago)? - Lemmy.World

It was a sparkling lemonade/soda with zero sugar or calories, but still tasted sweet enough and highly refreshing when cold. Would also accept a replacement for the non-diet version, which in my region of the US was unavailable even before they got rid of the diet version.
