HI Daisy,
you've seen Vicky's reply, to that I would add: google for Dukan - there are some blogs and press articles that give you reviews and personal experiences. Definitely buy the book if you're serious. And read it before you start - at least the first chapters, including the one about the attack and consolidation phase.
Think carefully about when you start, the first few days are hard. I especially waited until a Tuesday when I'm at work and not at home and going swimming with a 3-year old.
Make a food plan so you don't get bored. I hope you like fish and eggs otherwise you will get bored.
Make sure you have all the right ingredients at home, including oatbran (very important, it's not the same as porridge oats). Try not to have tempting other stuff lying around (ok tricky if you have a family)
If you do have a family and normally eat together, try and plan you meals so that you can eat with them and still have nearly the same. Example: we had family visiting so we had roast chicken & everything and I just had chicken meat and some veg, everyone else had roast potatoes & gravy etc. Grilled lean meats, poached fish, all work for this set-up.
I found it remarkably easy. No cravings, no hunger. After 4 days attack and no side effects I had one really bad day with stomach cramps as my system adjusted to digesting nothing but protein (I suspect) but that went away and not happened since.
Try not to buy any prepared foods, if you do, read the labels very carefully. There are hidden carbs in the shape of starches and sugars in all sorts of cooked meats and low-fat joghurts.
Stick to the list, there are no exceptions
