What you could do is get some store brand soda water / club soda / seltzer or a non-sodastream water carbonator. Then get like a cola syrup online. I know some ones that do use sugar are 1883 and Torani, they both have a cola flavour. I also havent seen a lot but I saw one brand called Zerup that has a zero sugar cola syrup. You could try that.
The flavor of Coke Zero with preferably no sugar but doesn’t have to be that way

That’s a great idea! I do have a carbonator!
