Nice one mate, I am glad to hear your EC has improved. So much of this forum is dedicated to theories and potential cures (and rightly so) but it's always nice to hear of a success story once in a while.
I've also found that stress definitely plays a part. If I don't think about my lips, they don't dry up and peel as much.
Just one question though, do you still get all that white stuff when your lips get wet? and if so, has it reduced at all?
