Mucous
I would try Mucinex also, plus increase your NAC to twice a day if you are only taking it once a day. I also use the Bragg's vinegar drink to keep mucous down. 2 teaspoons of Bragg's organic apple cider vinegar, 2 tsps raw organic honey mixed in one glass of water. I take it in the morning before I eat. If I feel like I need it, I take it again in the afternnoon. The Bragg's book recommends 3 times a day, but then they are the ones selling the vinegar. If you don't know anything about the Bragg family, they are health oriented people who look 30 years younger than they are and hang around with Jack LaLanne. I thought the vinegar drink might taste funny, but I have grown to like it. One thing that Rose mentioned is to not discontinue meds or lower O2 until your body is really ready. I would avoid that nasty pulmo unless you feel you are getting a respiratory infection that you can't shake. Don't let things go too far if you truly feel you need medical help. In the meantime, don't be too eager to do away with your former routine. You are still very early on yet and your lungs need all the help they can get. I went through several periods of increased mucous. That's all it was, increased mucous. I have no answers as to why, but you can try to keep it down with the suggestions given.
