LOL at Pistey trying to pretend she's drinking water!

Look, people, if you haven't done low carbing before it's really, really important that you get your head round it so that you know what it's all about and why you're doing it.
There's a massive amount of both ignorance and prejudice about low carbing, and you will quite often come across people who tell you it's dangerous, and you'd be much better off doing a low calorie/low fat diet.
The fact is, most of us will end up eating a better diet once we remove all those overly-processed white carbs. What on earth can be wrong with a meal that consists of meat/fish with fresh veg/salad?
And yes, if all you're eating now is biscuits, cake, toast and chocolate then chances are you will feel a bit crap for the first couple of days. Again, if you have read up about low carbing then you will understand why this is, and why it's important to get past these first couple of days.
It's also why there has been a 'notice period' about the bootcamp coming up!
Once you're in ketosis - generally after 2-3 days - you won't feel as hungry. But if you are hungry then eat something. The whole point of this WOE (way of eating) is that it isn't a diet. There should be no deprivation involved. OK, to start with you can't eat certain foods, but once you're at a weight you are happy with, then most carbs can be re-introduced in small quantities - and you can have the odd cheat now and then without doing too much harm.
BUT THE WHOLE POINT OF THIS TWO WEEK BOOTCAMP IS TO GET YOU ALL UNDERWAY AND TO LOSE A REASONABLE AMOUNT OF WEIGHT. THAT IS WHY IT IS SO STRICT!
If you don't want to join it, I can quite understand. It isn't intended to be easy peasy. But it is intended to shift some weight.
OhThisisJustGrape - that sounds like a very severe reaction to me, and it doesn't sound like just carb withdrawal, unless you have just stopped eating altogether. This is not a diet where you do that, at all. You should be eating proper meals, three times a day - with snacks if you really need to. To be honest, it sounds like you have serious issues with food, and I'm not surprised your DH is worried about you. What have your meals been since Wednesday? You really, really have to eat! Have you read all of this thread properly?
