Dear Jo,
What about having some cottage cheese or yogurt for breakfast?
Please eat some more protein thru out the day...your blood sugars are probably fluctuating and is contributing to mood swings as well as carb cravings.
Have you ever tried the low carb meal replacement bars or shakes?
It is a way to get more protein in your diet and I think they taste pretty good.
South beach diet makes a couple that I like...kind of like a rice crispy bar with chocolate.
It uses sugar alcohols as a sweetener along with splenda and is very satisfiying. One bar has around 200 calories and costs about $1.25 a bar in the 6 bars to a box.

Do you like hard boiled eggs?
I have boiled a dozen and then keep them ready to be eaten when I don't feel like fussing with a meal.
2 eggs is a great source of protein and very inexpensive.
In the past I have scrambled eggs with brocolli and cheese for a really satisfying meal any time of the day.
I also use a bit of tony sacheres spices to give it a little kick.
I have recently remembered how a one ounce cheese stick of mozarella cheese, 80 calories...eating 2 of them is a very satisfying snack.
I have sun flower seeds and pumpkin seeds and peanuts also to snack on when I get muchy in the evenings.
I also discovered they make 100 calorie bags of popcorn that are really good!
The 9pm snacking cravings are really a killer and I used to eat 3 ice cream bars...(i ate a box of 12 in a week)now I just don't buy them....I don't have the will power if they are around.
