Yes. Mine didn't start until I had finished taking it. I blamed it on something else, but reading your post makes me think it was the Kroeger's. During the cleanse, I had a lot of worms (strongyloides) come out of my scalp and my face. I had terrible sores all in my head. Shortly after I stopped taking it, the sores all healed and my hair started falling out. I stopped 4 days before the end because I was having such horrible die-off and because of all the sores opening up all over my body, but especially on my face. Now I have terrible scarring from them, not like the pockmarks of acne, but long scars like something tore through my skin. The sores were oozing and crusting. It was horrible.
