I'm trying something similar to your protocol...
I had a flu and ended up stopping to wash my mouth with baking soda, within 2 days the white line between the lips began to form again
Looks like is more hard than I thought get free from this..
Anyway my lips do not peel any more, but I keep it with bepanthol on and on
Today I will see the results of a spittle exam I did...
I fear about the white stuff in mouth maybe coming from the stomach...
Really nice news! =]
