Soda, not really a fan of mineral water, and I've never tried root beer. I prefer still drinks if I'm honest though, I've been trying to drink increasingly less soda over the past few months as I decided it's time for a change.
Of the options I don't really drink any of them straight. I only really drink pop if I'm mixing it with alcohol; and I only drink soda water if I'm mixing it with lime cordial. I've never tried root beer.
Hate to say it but I don't drink any of those. Soda, very rarely. I'm not a big fan of anything carbonated. Not for health reasons, I just don't like the fizziness I guess? Even when I was a kid I wasn't big on soda, aha.
99% of what I drink is just water. I just drink it constantly, I know people who hate water but I've just always been super into it for some reason.
