I dont know if totally cured but everyone i see on tv seems to lick there lips and there lips are totally normal. All the president and vice presidents do it i did it as a child and never got ec. I have pictures of me as a kid with great lips and it shows saliva on them. Do you have dogs? They lick all the time and human an animal saliva is the same. It also relieves stress to lick your lips because it has cortisol or somthing in it and ec may be stress induced. The Wikipedia page on saliva says it is 98 percent water and contains things like epithilliel cells growth factors elecrolytes nutrients. Just read the page. My pychologist said dont believe everything you read on the internet like saliva digesting your lips because of enzymes enzymes only digest food not your skin.
