great i think you will have much success i believe in you.
the white film is sign of the thrush or candida, did you have a white tongue as well? check the roof of your mouth is it white? next are you prone to canker sores? i had all these. make sure you put the liquid Lactobacillus acidophilus directly on the triangle area and on the lower lip and get the area were the inner mouth turns into the lip, let it dry. the triangle area was the last to heal for me do not peel this at all during the treatment if it happens to fall off when brushing teeth or eating or whatever that's okay, just no forcefully peeling. that area is really prone to taking more skin than you want, at least for me it was.
a huge factor i forgot to mention is try not to look at your lips in the mirror know it sounds weird but during this time i just stopped caring and took my supplements and followed a low Sugar diet eating steamed vegetables and rice with beans as the main course the rest was yogurt. eventually the tight lip feeling which was a constant through out the day, decreased i would maybe feel it 2-3 times a day and i would apply the iquid Lactobacillus acidophilus let it dry or if i was at work i would use a light layer of avalon organics lib balm and dab it on only the lower lip. you can do it trust me many people have cured this.
