I have been on a parasite clease for about 4 or so days now. I week before that, I did Schulze IF#. I just went to the bathroom, (urine only) and when I got up to flush, I noticed these specks on the walls of the bowl of the toilet. It looks like someone had sprinked pepper in the toilet. I thought at first that maybe my husband trimmed his beard over the toilet, but I then remember that I had used the toilet only an hour or so before (long after he had done his morning grooming) and the specks were not there. Also, his hair is not black. So I flushed the toilet to see if they would go down and they did not. I flushed it a second time and took some toilet paper and wiped at them. They did not come off overly easily, but did eventually come off. It can't be mold, for as I said, I had already used the toilet that morning before the time I noticed them and the stuff was not there. Mold does not form in a matter of an hour's time. Could this somehow be related to the parasite cleanse? Thanks.
