Soph, I hate porridge so have not chosen that at all, I have some soup to try but I'm not the biggest fan of soup so I'm worried about it! My Consultant said I could add chilli to it and pepper to spice it up a bit. I just need something hot! I tried a chocolate shake hot and it was vile :S so I won't do that again!
I know I'm in ketosis because of my breath. My husband tells me when it's bad and I have a mouth wash and stuff to hand! I can taste a metallic taste in my mouth pretty much all of the time too. You used to be able to buy ketosticks from the chemist, not sure if you still can but might be worth trying.
Do you know anyone who has done Cambridge successfully? I do, a lady I know did it last year, lost 8 stone and went from a 24 to a 12....she is my inspiration!
