Hiya, looks like we started the same day! :-D I haven't done cambridge before.. first timer! :-o I do know someone who has and lost loads on it, which made me decide to give it a go. I felt deflated and had a headache too last night, but as soon as I got myself to do something to keep my mind busy, I seemed to be fine :-D the morning was the hardest though but as soon as I had my lunch it seemed I was fine, but then I was busy for the rest of the day. I think the key to success on this diet is to keep your mind on other things lol!
Awww I'm glad to hear it worked for you last time! :-D Fingers crossed we get through these first few days and hopefully it'll get easier then :-D
