have you tryed a nebulizer? you should ask you dr. about it it dose a grate job for me when my breathing gets real bad,I have copd there are also some aromatherapy stems that will help if mine is not super bad I use them insted of the nebulizer. I make all my own natureral steams,face masks,body lotions,and body scrubs,it's fun to do and they work much better the the crap you get in stores,at least I know what is in them no cemicals
