Hi Debbie
Don't worry - you'll get a great loss this week and by then you'll be in ketosis so won't feel anywhere near so hungry.
In my first few weeks I dreamed about food most nights, and used to wake up feeling guilty because in my dreams I usually gave in. It's amazing how bad I felt even though I knew it was a dream. I think it helped though because I haven't cheated at all so far. The dreams stopped after about 3 or 4 weeks.
You've chosen a great diet - I'm assuming you've not done it before. It has completely changed my life and I get passionate about it, but if you stick to the rules exactly (and they are very easy) you will lose your weight in no time.
Best of luck Debbie - and let us know how you get on.
Jon
