I have read each and every post before replying.
Sugar is very addictive. Unless you have that addiction it is somewhat hard to understand. Many alcoholics and drug addicts turn to sugar after quitting drinking and drugging. Ask a chemical dependency counselor, they will confirm this.
Some people can have a small amount of sugar and move on. Others cannot. Any number of foods can be a trigger food for some. Most seem to be foods with a high sugar content. Eating these foods can start a binge with a compulsive eater. Sugar is really just another drug to many. That is why our country is so overweight. There are lots of compulsive eaters in the US.
It really isn't about willpower for some of us. We have all the willpower in the world to do other things.
There are may reasons people overeat. Lots stem from emotional issues. Overeaters Anonymous deals with lots of stuff like this.
Good luck to all who deal with this. Stopping sugar and totally abstaining will help immensely.
