Nancy feels like your sister. When you are a sugar addict, saying no is not an issue of willpower. Your biochemistry has a direct effect on your behavior. Your craving and desire for sugar are profoundly affected by your brain chemistry, and even more significant, by what and when you eat. You are a sugar addict because you are sugar sensitive.
Sugar addiction is a primary symptom of sugar sensitivity.
If you are sugar sensitive and your meals are erratic, if you skip breakfast, eat lots of sweet things, drink quarts of diet soda or eat pounds of pasta and bread, then you will be depressed, moody, erratic, volatile, forgetful, and impulsive. You may have a short fuse, a short attention span, and a reputation for being all over the place. You may have trouble with your weight, you may have an eating disorder, or you may have a problem with aggression. It has probably not occurred to you that the food you eat could have such a dramatic effect on you. You have to go out and get a pint of your special brand of ice cream even if it's eleven o'clock at night.
