Hi Kim,
I do treat myself to 2/3 cans of coke zero a week. It stops me nibbling food and haven't found that it affects my weight loss.
I'm sure a lot of people on here wouldn't agree with me. You just need to do what's right for you.
I've just been in the town and I forgot to buy one!! It'll need to wait till tomorrow now! I suppose you could make them with the water flavourings too for a change.
I was thinking of doing chocolate tetra ice-cubes, so I could have little ice-creams now and again. I like the idea of the ice-lolly kit .... I may have to adapt my plans.
