Maybe many of you have already read Andreas's response. But I just wanted to reinforce to those of you who have not, that Andreas's diagnosis definately makes sense to me.
There is a message in the 'Ask Andreas' Forum by #43814 on 4/11/2005 titled 'Dry, cracking, peeling lips.' This person's description of their lip condition was very similar to my own. When I clicked on the reply by Andreas, I was facinated by his diagnosis and think he is right.
John G has obviously taken the advise of Andreas/Curezone as well and it appears to be working for him. (Remember, he had the condition for 15 years).
So if you are still looking for answers, please check out the above message by #43814 and the reply from Andreas.
