Welcome, rusmum! As Willie has said, the next Bootcamp is starting on 29 April. In the meantime, I really recommend that you read up on it (using the stuff that she has linked to on the spreadsheet) and get yourself prepared for low carbing. The key to success, IMHO, is preparation and planning. Make sure that you have plenty of low carb foods to hand, and plan your meals. This is especially important if you're on the go and away from home - make sure you know what you're going to eat and where you can buy low carb options.
The other thing to warn you about is the carb flu. If you're a complete carboholic, you are likely to feel pretty shit in the first 2-3 days, whilst you 'withdraw' from the carbs. Drink plenty of water and keep your sodium, potassium and magnesium levels up by eating salt (or drinking a hot drink made from Marmite/Bovril), spinach, avocado and salmon. It will pass and you will feel much better in a short time.
AuntieMaggie I've just weight a small-ish avocado that I have in my fruit bowl, and it weighed 124g - so I'm guessing that once the peel/stone has been removed, that will probably be around 100g.
Hopefully on day 2 you will be less hungry. It's also, from memory, a slightly higher carb day. But if you are hungry, eat something. A hard boiled egg, or some prawns (if you have any left!) or a piece of ham, etc.
