Many thanks to everyone who posted advice on this. The Champagne I fear wasn't in a bottle only in some strawberry conserve so not exactly in quantity.
I've managed to give most of it away including the iced biscuits which must be a first, but I fear am still too greedy to follow all the most virtuous advice and having been out to another pre Christmas tea party recently, I came home and ate the nuts. I think though, I am learning more self control - I think !! Good luck to you all.
