Hi Jennifer. Pretty sure what I have going on is allergies to the animals in my house. I was doing very well until animals moved in. My nose runs constantly, my eyes itch, sneezing my head off, and coughing up stuff......The color of what I was coughing up had been clear, but as of today; it is starting to take on color. I am going to see about getting that med that Lori suggested to feed the cat to convert it's saliva protein to something less noxious. Plus, I think I need my own room to myself. My daughter and both animals pile into my bed every night and sleep. Although we all love the togetherness, I think I need to sleep alone. (although I know that is impossible as my dog will not separate from me.) But, I can at least eliminate the cat.
