The book says to use OJ or grapefruit juice to break the fast. So it looks like it's citrus no matter what you do. Different fasts suggest breaking using different methods. Paul Bragg's Miracle of Fasting book said to use a cabbage salad. It's been a while since I've read it, so I don't remember all of the details. Maybe you could look at other fasts and see if the breaking portion might help you out since you seem to be having an issue with citrus.
