As MamaCaz says, tonic water. It is my favourite fall back when on driving duty or when I just don’t fancy anything alcoholic. Having said that, it is the only fizzy drink I will countenance, and I do, very occasionally, like a large measure of Tanqueray in it! I have stopped buying wine except when we are expecting people for a meal, because invariably, I am the only one who wants to finish the bottle once it is open (over days, though, not all at once, but still!), and, as indicated above, it is full of calories ?! If I don’t buy it, I can’t drink it.
