I still think that making war on bacteria is a mistake, since they cannot exist without food.
The food of bad bugs is dead human cells killed by poisons that we eat - this includes the stuff from tooth caps, stored mercury from long gone fillings, and above all carbohydrates.
There is no evidence that our paleolithic ancestors ever ate any carbs, certainly not the fruit etc. developed by neolithic farmers.
A healthy human body contains about 4 pounds of microbes; they make all the vitamins we need and can even transmute elements which we don't get in our diet.
That's if we treat them right.
Your gut critters have been treated wrong.
I suggest meditation on the subject of critter abuse.
