Yogurt is OK if you are not lactose intolerant. Yes on food items.
Think of it this way: When our pets are sick the vet will often recommend white rice and boiled hamburger. Low fiber gives the guts a rest. Why not us too?
Maybe buy 2 magnesiums. I have a friend who has used 2 at one time. Not sure I would drink both right away though. I still can't get him to stop the wheat, lots of soluble fiber in grains. If it is whole wheat there is also a lot of insoluble fiber.
We can not digest insoluble fiber. But, the often times not friendly bacteria in the colon can!
ps I took the powdered form of magnesium citrate.
When I got into trouble was just after I did the Wormwood , cloves, and Black-Walnut hull tincture. It just made mine mad, they clumped together for protection and they plugged me up.
I opted for the RX. I did not realize how many were there.
I backtracked and figured out when and where, friends dog and I worked on vehicle on ground where dog had pooped. Boy was that dumb. I still thought I was invincible then. Toxocaris, I am sure was my lung (walking pneumonia) troubles for almost 5 years.

I drink the entire bottle with some Sugar free cool aid then prepare to go all day.

SIBO is small intestine bacterial overgrowth. SIYO is small intestine yeast overgrowth. parasites move around between organs (intestines) and other areas (lymph). The bacterial infection gets into the organs (GI tract) and your gut gets sick.

To prevent this, it is a good idea to cure your parasites of infection, and cure your parasites of parasites. Do this by a progression of natural products, which clear the lymph, blood, and other body tissues of these infections.

Once your body is healthy enough to go after a bigger target (harmful worms). I was able to get myself into a much better place, using minerals and metals. Once in this better place, you have the time to work on parasite issues.

Figuring out which parasites you have, and what to try to do about them, takes time. I went through the full gamut of health issues, and I guess progressed from the obvious to the obscure.

Getting your body into this healthier state helps guide you through the subtle war one rages against parasites.

Also be aware parasitology uses conflicting terminology. Migrans is a family of worms, also a Larval phase of certain parasites. This means you could be infected with Migrans, or your parasite infection Ascaris, is in a Migrans growth phase. This kind of duplicitoususe of terms, makes parasitology an difficult art.

Take 1/3 of your time and dedicate it to doing things that make you feel healthier. If it is a salad, or a bath, these are choices you can make. I like cooking. It takes time, but the body still needs to eat.
