I've been keeping a journal noting all the improvements I' m noticing and there are quite a few. By the way, nails are growing better and seem stronger and my skin is more moist. Also went for an eye exam and my vision has improved. I switched to a weaker prescription. Yes, I wear contacts because I can't stand glasses on my face. Dark circles have gotten much lighter. My face is much more lifted. I used to feel a wheezing sensation when I'd inhale deeply I have a hiatal hernia, anyway that is completely gone. It's amazing.
