Or maybe it's AD therapy. But antibiotics do screw up my good bowel bacteria and constipate me but I do tend towards that. When kids were small with ear infections, their doc would prescribe a something pills to promote growth of "good" bowel bacteria. Think nurse was AD therapy. If I don't do it, loose info in my head. I just finished antibiotics for a UTI and am eating Activia right now (yogurt can help bacteria grow.(good)
