OK, of all the recipes, this one is technically not sugar free. We ummed and aahed about putting it in, because maple syrup, although much better for you than sugar, is still a sugar.
But, and here comes the big but. For some people, a cola addiction is nearly impossible to kick, but unbelievably dangerous (even more so a diet cola addiction). So with this in mind, we have a cola substitute. But please, only use
this to kick your cola addiction. First replace all the cola you drink with this, then cut down on the amount of maple syrup in your cola until you are left with plain old soda water.
