I don't know Fresca, but I moved to Coke Zero a while ago, and also started mixing it with carbonated water.For a long while, Fresca was the only artificially sweetened drink I could stomach. The grapefuit flavor worked with the aftertaste of the sweetener, and since I like grapefruit, it was okay for me.
Then, in an effort to eliminate sugared beverages from my diet, I used it as a gateway, and got myself accustomed to Diet Coke and Coke Zero, and a couple of others - just to find out that at moderate doses, artificial sweeteners are a migraine trigger for me. :/
You still get some of the waste and sweetness, but not as much, making it also easier to enjoy less sweetened food and beverages. Some will find this sacrilegious, of course.
Not sure how feasible that is in the US, I remember the terrible chlorine taste common for tap water in some US regions, and that buying carbonated mineral water was unusual and seemed more expensive than in Germany.
