What kills off bad bacteria, kills off good stuff.
I just finished reading a book called *The Good Gut*, and while probiotics are good to take during and after a course of antibiotics, the author contends that antibiotics permanently alter the gut microbiome and not for the good.
It was a very interesting book, and might be able to be had from the local library if someone doesn’t want to buy it.
Very true, but if your lungs are shot your gut doesn’t much matter.
