I'm also eating more than I should. I am going in for a refill. I was banded on 11/18/09. I can eat anything, and hardly ever feel that I am restricted. I am loosing about 2 pounds each week. Sometimes it fluctuates back and forth, according to what type of foods I'm eating, but it always goes back down, with an average of 2 pounds a week.
I find that eating chicken or meats, that I do feel the restriction, but eating soups, salads, and vegetables, I do not. I'm ok with this though. I was told by my doctor, that loosing 2 pounds a week is excellent. You do not want to loose too quickly or you will have more loose flab. If you lose it slowly, it will tend to shrink with the weight loss. I have not lost enough for me to know this yet, but I'm hoping.
Most the time I eat what I know is good for me, but there are times when I eat things that I know that I should not, and I'm still loosing. Between meals I eat nuts (pecans, peanuts, walnuts, etc) to tide me over. These are good fats and proteins. I was on the atkins diet before doing the surgery, and it worked great for me. I just could not keep loosing on the diet. My body would get to a stand-still and not loose any more, and of course, I would gain it all back. I found out a lot of good information from being on it though. Eating Good fats with Proteins will burn themselves up and not put fat on the body. That is what makes the atkins diet so great. Nuts have the good fat and protein. Beef jerky also helps me.
I also agree that you should not think of it as a snack, but just something to tide you over. Just a small amount, eaten very slowly will make a world of difference. Good luck.
