Thanks very much for the kind words.
Sally, I looked up that Sodastream device and I just GOTTA have it. It's relatively cheap, easy, with loads & loads of flavours, and as I like very lightly carbonated water (which for some reason is always more expensive here), this is just *ideal*.
We're also happy to live in a place where the tap water is constantly of a higher quality than any kind of bottled water, so how much better can it get!
