Emmy with your chocolate cravings, you are allowed some brands of dark chocolate. I have co-op Fairtrade dark chocolate, its 8g carbs for half of quite a big bar, so i just have a few squares now and then when i need it.
You are deffo eating the right things, i would suggest changing what you eat completely as if you've been eaten the same stuff for s while, your body may have got used to it. Heres what i have to give you some ideas:
Breakfast- An Atkins shake
Lunch- chicken and goats cheese salad
Snacks- pork scratchings and pieces of cheese
Tea- beef burgers (no bun or chips!)/ fish/ cornbeef and cheese/ chicken
Hope this helps xx
