sodium chloride and acetlysisteine back ordered and unavailable

I have been out of two of my most needed nebulized medicines. Apparently there is a shortage of both of these and getting them from my pharmacy has been a nightmare. I have been waiting for a few days and still no meds. I don't know what i am going to do . I ve called a few pharmacies and they all have given me the same answer they are all back ordered , And they haven't a clue as to when these meds will come in. Shortages and delivery issues. I am just hoping that i will be okay since these meds keep my lungs clear the best they can . I am doing okay but, I dont know for how long.
