Last year I tried the CD for 3 weeks. Unfortuatley I had to stop because I felt very ill. Cant remember what my weight loss was but it was good for the first week. The second and third weeks were a blurr. My mouth and tongue were sore and felt like they were on fire. My breath was awful like acetone. I was drinking litres and litres of water and still extremely thirsty. As soon as I stopped the diet and ate and drank normally the sore mouth and tongue went and I recovered. Has anyone else ever had this. My counsellor had not heard of this problem before.
