Hi louisa,
 
I started the CD this morning and I am having just tetra bricks and soup.  My CDC has just advised me to drink more water.  Im not really keen on the packets but I dont mind the soups and much prefer the convinience of having them ready made. As there are only 2 flavours im having 1 choc and 1 banana each day plus a soup in the evenings.
 
Good luck xx
