I actually don't drink much water, but when I do it's almost always still but I will drink sparkling on occasion. I'm actually trying to change this and start drinking more water.
I would say still water every time. I noticed though, when i was in Germany they seem to drink alot of sparkling water. Everything seemed to be diluted with sparkling water. I don't like the taste of it myself, but each to their own.
Go sparkling water! Still is hmm, boring? :lol: Oh well... sparkling water has a disadvantage: it makes me burp :lol: But in the other hand, its "taste" (if you can call it taste) isn't as bitter as still's.
