Good for you that you've found something (acidophilus liquid) that has drastically improved your lips!
So that others here can figure out if their cheilitis is similar to yours, and therefore might be treated in the same way as yours, can you describe all the cheilitis symptoms you've had, how long you've had them, etc.?
I know that you have often complained about having a white line of wet stuff on your lips.
What other symptoms of lip irritation and exfoliation did you have? Did you have a lot of dry skin buildup, layers of dry skin rising up on their own from your lips, pockets of air forming underneath your top lip layer, cracks and bleeding in your lip surface?
