So I had my first attempt last night!!! I only had 2 rice cakes at lunchtime, no snacks or breakfast, then didn't have dinner until about 8.30pm which was grilled veggies and some halloumi, followed by a little frosting free cupcake that DS1 and I made yesterday afternoon and 3 sugar free sweets. Drowned myself in diet coke as well all day with a couple of pep teas and coffees thrown in for good measure!
