This article is full of interesting information about the after-effects of antibiotics, including difficult-to-treat things like candida and other fungal overgrowths which can lead to such things as arthritis, lupus, IBS, etc. Also implicated in cancer, diabetes, you name it! Suggests natural (non-drug)treatments.
