Hi Frances,
Good question. I did reply to your post but somehow don't see it on the website, so maybe it is hiding somewhere!
Basically I said when you stop using a coping method such as overeating to manage emotions, they will come up more easily, and it is natural to worry it is going to get out of control. The same thing happens when someone gives up smoking and they become more irritable and emotional for a while.
The key thing is to find ways to manage this which is exactly your question. One thing I would suggest is to create regular times when you can pay some attention to your emotional insides, so you can drain off some of the build up. Sitting down on your own with a notebook to write about how you feel and where you feel it in your body is one way. Even better find a buddy to talk to about how you feel about your week, your life and you.
By letting feelings out bit by bit, they are less likely to spill out at the wrong time. Key ways to express them are talking, laughing, tears. There are others too depending on the emotion. Hope that helps.
