Seriously, though, I'm afraid I do love water. Just plain water. Absolutely my drink of choice... has been ever since I was a little girl. No idea why, but threads like this, and living with another soft drinks addict, make me very glad it's the case!
Pukka do some actually tasty herb teas. Another one you might try is the Teapigs range - especially mint and liquorice, which is utterly delicious.
If you find any way to break the addiction (and, from what I've seen, there's really no other word for it), I'd love to know!
