That's a good point. My father smoked until I was about 8 yrs old - although I don't remember him smoking in the house. He probably did, though. And I had asthma until I was in my 20's. I guess it shouldn't be surprising that my lungs are screwed up but I'm surprised anyway. I'm coughing a little less today so maybe it's starting to ease up. My throat is actually raw from all the coughing. So far, I don't feel very well on this fast, which is probably because I have a lot of toxins in my body. I don't take medications, either. Thanks for your thoughts.
