Hi Nell - have you come off CD now then?
If not, then you'd be best off sticking to the CD soups. They have one third of all your daily nutritional requirements - a 10 cal soup won't. If you don't get all your vitamins and things, you'll get ill!
You've had a fantastic loss! Is that you at target then? If so, why don't you discuss the CD maintenance plan with your CDC - going through it carefully is the only way to make sure you don't put all the weight back on really quickly.
