Since a few people have cured their EC going on very strict diets most of us could not tolerate, maybe this has to do with a digestion problem (at least for some of us). If you haven't tried experimenting with different digestive enzyme supplements for different absorption problems, I would see if it improves your lips. Not all the same digestive enzymes work for different digestion problems or you need to figure out which digestion probelm you have. One way to find out is to experiment with different digestive enzymes.You need to try something new if you're not getting anywhere trying the same thing time after time.
