TheGrinch - not for the first two weeks of Bootcamp. It's really important that you eat breakfast.
Handsup you will struggle until your body has switched from carb-burning to fat-burning, I'm afraid. Don't push yourself too much during the next two weeks. You will, however, find that you will soon be back to doing whatever exercise you're used to - and may even find that your performance is even better! There's a really good book called The Art and Science of Low Carbohydrate Performance by Drs Volek & Phinney that's really worth reading
mootime when you say DS is ok with you eating cheese, does that mean you're breast-feeding?
sass - how about cheese? Makes a great low carb snack. Sorry to hear you've had a funny turn - are you on day one? Make sure you're keeping your electrolytes balanced - which means getting plenty of sodium (salt), magnesium and potassium. Salmon, spinach, avocado and natural yoghurt are all good. Try drinking a hot drink made with Oxo/Bovril or Marmite for the salt, as well as cooking with it and adding it to your food.
lurking stock cubes and soy sauce are OK in moderation as they do add carbs. Just go easy!
Juan you will get used to it 
Nake NO, NO, NO AND NO! NO SUGAR ON BOOTCAMP!
Mushroom butternut squash is too carby - although carb counts do vary! I've seen figures around 7 or up to 10g carbs per 100g, so I wouldn't risk it
janx - same advice as for sass!

B- avocado in olive oil and a BPC
BPC
L- chicken salad with roast chicken, lettuce, cucumber and mayo
D- roast chicken with baked sweet potato and lots of butter.
^This is all fine apart from the sweet potato! Way, way too carby.
Yesterday I had
B- 3 egg omelette with onion and courgette and a BPC
BPC
L- roast chicken and avocado salad with olive oil
D-chicken and brocolli and lots of butter.
^This is good - I hope you're eating the skin of the chicken? If you can, substitute the onion with shallot - it's only 3.3g carbs per 100g, compared with 7.9g for the onion.
