Oh no, are you doing SS?
Perhaps you could move up to one of the higher plans and then move down. eg. do 810 for a few days/week, then SS+, then SS. This might give your body time to adjust.
Also, is it hunger that makes you eat or cravings? I find before I get into ketosis is isn't so much hunger that effects me but I crave absolutely everything.
Start again tomorrow, keep yourself busy all day and go to bed early (was it you that did the earlier thread about that?), I often found for the first few days I would head to the bath or bed just as something to keep me occupied. Also tomorrow, post on here when you think you are wavering, I am sure there will be someone around to give you moral support.
And finally, think of it this way, despite eating you probably still didn't eat as much as you usually would as you had 2 Cambridge meals.
Also what constitutes a binge? In the old days a binge for me would be a whole Dominoes pizza, these days it is a pack of chicken. Keep things in perspective.
It's not the end of the world, disappointing after all your hard work all day but you can still do it. You will still be nearer to ketosis than when you started.
