Hey Colette, really hearing you on the challenge of deciding whether to do full Dukan, knowing it works when you do it properly, or to find some other way that's not quite so restrictive. You will succeed whatever you choose though as you definitely know what works. Wonder if you could do Dukan properly, with all your planning etc, but allow yourself some slightly non-Dukan foods to alleviate boredom. I'm thinking slightly fattier meats like lamb, beef and pork, rather than cake though! If boredom's the thing that's hampering your efforts, I'd definitely focus on finding ways to overcome it. Do you like Asian flavours? I've been really enjoying fish cooked with ginger, chilli and soya sauce - tastes so flavoursome but still Dukan, especially if you use white fish.
When are these birthdays coming up? Definitely something to aim for!!
