>The tic tacs labeled "sugar free" use artificial sweetener.

I've sort of trained myself to be careful at this point, but this is an annoyance of mine especially with clear sparkling water. I'm fine with and generally like seltzers without sweeteners added. I hate sparkling water with some artificial sweetener and the difference isn't always obvious from the big print on the label.

Look for “no sweeteners” on the label and/or check the ingredients list.

Hence "big print." You need to look carefully which I do unless it's a brand I know that only sells unsweetened seltzers.
