When I first had my CF/F, I had my doctor check for parasites. It always came back negative.
When I started h2o2 therapy, and h2o2 colonics, I had so many dead ones in the toilet.
I wanted to take them to her as a sort of show and tell haha
If your specialist does find some, then you have even more than they think.
And if they don't find any, you probably still do.
I used to think they were gross. But now I know they just need a good anaerobic home, with lots of unnatural sugars, and low organic minerals, to be happy.
