I have been on 7% saline now twice daily for about 2 weeks. Starting to feel like I can breathe again and my cough is almost gone. I even went for a bike ride this weekend; first in several month. So thankful for the advice of this group. I also ordered the Aerobika and add that to neb time. Wondering about chest percussion vests; any favorites? A friend recommended the Volara but would love the group input. Thanks
