Family pets symptoms and conditions

I was on the low dose, 100/50, for 2 years. I had blurry vision in my right eye and lethargy. Last week I woke up and could not breathe AT ALL. I was choking for about 45 seconds with no air coming in. I have read that Advair can bring on sleep apnea. After a couple of days of doing research, I stopped cold turkey. My vision cleared up in a day and my lethargy is gone. I am now using apple cider vinegar for my asthma (brought on by my 2 dogs and cat) and so far, all is well. How that stuff is legal, I don't know.
