I am on the Cambridge/slim and save (I use the Cambridge drinks and the slim and save bars because I cannot choke down the CD bars lol) I am sick of water and have started drinking the occasional glass of coke zero. I will drink maybe a bottle in 7 days, so about a glass a day. I also decided to make some into a jelly using pork gelatine. I was under the impression that coke zero was okay, because it's zero carbs and doesn't contain citric acid, but now I'm reading that aspartame isn't allowed on low carb diets? Am I doing something I shouldn't? I drink coffee and that hasn't stalled me, so I'm not sensitive to that. If any CD councillors see this or someone who know's the answer, I'd be very grateful if you'd reply My CD councillor is on holiday, which is why I am not able to ask her.
