For those few who have been cheating all of you, one thing I picked up from another low carb forum I used to use is something called The 3 Day Experiment. No idea why it's called that!
But it's three days of lean protein, low fat and virtually zero carbs.
You are apparently able to lose up to 5lbs following this. If you've really been overdoing the carbs, this will help - I imagine it's about forcing your body to use the re-filled glycogen stores, although I'm guessing wildly here!
So you eat three times a day, but only have protein, and keep it very low fat. So boiled or poached eggs for breakfast rather the fried or scrambled with butter.
A tin of tuna in brine rather than oil for lunch, and a chicken breast (no skin) or two, for dinner.
Lots of water but no milk - so tea and/or coffee black only.
After the three days, you re-introduce carbs slowly, so the first day would be to introduce a salad or some similarly really low carb veg, and for the couple of days after that focus on ultra low carb veg, like mushrooms, celery or spinach, etc
It's hard, because it's really boring. And you'll be fantasising about a lettuce leaf halfway through day 2!
But it does help you get back on track.
If you want to try it, the best way I found to cope with it was to think of it divided into 9 meals; after each meal, I'd mentally count them off - 1/9 8 to go, 2/9 7 to go, etc
