1400 calories?

I binged some today.  Right now, I am struggling to eat 1400 calories per day.  I need to learn "addictive" food such as crackers and potaotes in moderation or not at all.  I have learned a lot not only about diet but about my eating habits.  I also need to exercise more as well.  I am going to stick to the 1400 calories in the next few days or so.  I also plan to even lower consumption of calories.  I have changed my calories low enough.  I eat way too many calories and have gained weight because of it.
