I am a DNR . I don’t intend to be rushed to the ER. I have a prescriptions in my cupboard to try to make me either stop the mucus attack, expand my airways and clear an attack. Or when all fails , I will start on morphine. I do not intend to live in fear. I am stage 4 my pulmonologist says . I am on 4 liters . I have never used albuteral. I take Musinex 1200 every 12 hours . I do drink a lot of water . Seems to keep the mucus thin and coming up easily. I understand ones fear. Try to be positive and calm . It will help . Blessed Be, Crystal
