How do we repair the damage done by antibiotics?

I want to raise another question that doesn't get raised here enough. The more I research the more I see peoples health who turned completely south after taking long term Antibiotics , just like mine.


So what we need to start asking is HOW do we repair the damage done by long term Antibiotics ?

My theory is that is does more than destroy probiotics, I think it severely dials down the immune system, and possibly reduces digestive secretions?
