Thanks for all of your answers. Unfortunately I can't have ACV or anything fermented because I'm also on a strict migraine diet which could be adding to my intestinal distress! That's weird about the honey, it's the only thing that seems to "heal" my lips a little. The other thing that works is vaseline but I'm trying to avoid that because of the petroleum. Up till now I've been lightly exfoliating my lips everyday but I will stop that for a while and see how it goes. I just started teaching when this all started happening and it's soooo embarrasing to have to stand up in front of students when you look like a freak!
