Looking at your situation, it seems that you have made sugar and carbs into a forbidden fruit
. The longer you stay away from your forbidden fruit, the more alluring it becomes, until you return to the "dark side" and resistance is futile. (Sounds a bit like a Star Wars movie, forgive me). According to the principles of behaviorism, every time you give in and binge, you are just reinforcing this pattern and it becomes more likely to happen again. Not a good way to go.
How about trying something a little different? Use the well-known principle of "putting on cue" or "stimulus control" -- which is described on the Psychology
page of the blog, about halfway down the page where the picture of the conductor's baton appears. You might want to go back and read this section: http://gettingstronger.org/psychology/
This method has been used successfully to extinguish or limit undesireable behaviors. The idea is to allow yourself to have your sugary or carbohydrate-rich treat, but only under specific circumstances. Then you gradually reduce the frequency of the stimulus circumstances to zero or some tolerably low level.
You can do this in a few different ways (choose whichever works for you):
1. Designate a certain very limited time period -- say a fixed one hour window on 3 or 4 days of the week --- when you are allowed to have your carb treat, and be very strict about observing it, but really enjoy it then. Be sure to stop when the hour is over, but enjoy it while it lasts! Decide on the days and time window at the beginning of each week and hold to it for that week. (If you want to be really strict about it, set a clock alarm or watch beeper to go off at the designated start and stop times). You can change the "schedule" once a week. Consider yourself as two people -- the "trainer" and the "trainee".
2. Designate a certain room or place where you can have the carb treat, and only have it there -- no exceptions. It's probably best if this room is not the kitchen or a room that you normally eat your treats in -- so you have to make a special effort to go there. Allow yourself to have the carb treat only in that room, never outside of it.
3. Decide that you will have your treat only in a social environment, with other people around. Or only with certain people. This is similar to the way that some alcoholics are able to get back into control of their bingeing -- they forgo drinking alone, and they allow their social inhibitions about appearing out of control to help limit them.
4. Find some other cue or signal that must be present for you to have your treat. It could be, for example, that you have to be playing a certain piece of music on the stereo. Or that you have to be wearing a certain hat or jacket. Whatever. And then you are in control of that cue.
All of these are examples of stimulus control, because the behavior (eating the carbs) can only
occur when the stimulus (a pre-arranged time or place or circumstance) is present. Be very regular and rigid about this for a while, at least a few weeks. Condition yourself so that you only have the treat under these very specific conditions. They can be frequent at first, but then begin to reduce the frequency of the "stimulus" gradually. In other words, cut back on the frequency of times you "allow" yourself to have the treat. Never allow yourself to respond to urges or whims -- eat only at "prearranged" times or in predesignated places. Do this gradually, maybe cutting out one of the "allowed" days every week. You don't even have to totally eliminate the carb treats -- you could allow yourself one day a week or every other week indefinitely into the future, if that works for you.
From my research, this approach of gradually cutting back and allowing a bad habit to occur only within strict pre-arranged bounds, has worked for many people to quit smoking, drugs, and other bad habits. It has also been used in training dolphins, dogs, etc. to give up bad habits. It sounds strange, but it is a proven method. The beauty of it this method is that it brings "uncontrollable" urges under control, and then gradually phases them out. I don't know if it will work for your sugar bingeing, but it might.
