I just wanted to share; I have always had what I considered a bad 'habit'. Excess phlem, hacking, and spitting, coughing up gross stuff. I recently read that it is store bought milk. So I got excited when my jersey was about to freshen (have a calf). I had already planned to milk her for family use. I made a conscious effort to keep in mind whether this phlem would stop after drinking GOOD milk.(so far for one month) I DID!!, But my experiment goes further: I recently had some minor surgury, so the doc put me on antibiotics..The phlem came back after 2 days of antibiotics. I should be off of them in 3 days, and I am anxious to see if it stops again. I know that the commercial dairies give constant low level antibiotics, among other atrosities, but I just thought this was interesting, please tell me if you do.
