Ginger beer (as in fancy ginger ale) + lime juice + bitters, well-iced, is quite tasty. It's a Moscow mule without the vodka. You can mess with adding tonic water if you miss the vodka taste. A splash of Luxardo syrup, cherry juice, blueberry purée, of any number of other little flourishes (lychee is notably great, tumeric is interesting) can make it extra special. I drink occasionally but I also enjoy these NA concoctions. It helps that I don't have friends who make it weird for anyone to not drink alcohol when we're out or at parties.

Bitters (e.g. Angostura) is typically alcoholic though isn't it?

I want the bitters so that I don't feel like I am cheating too much, now.

So is mouthwash but I doubt you put enough in to trip the drink past .1% ABV.

But this could be of importance for people stopping alcohol due to liver disease. But otherwise should not matter at all indeed!

I see what you did there. :)
