I've gotten into drinking Coke Zero, maybe two cans a day at times 
I think it's the 'fizz' that I enjoy, so I'm thinking of swapping to sparkling water and adding a no added sugar squash to start with if the sparkling water on its own is too bland.
I know it won't be good for me, but am I right to think it's got to be better than Coke as there isn't so many random things in it?
