About a month ago my breathing all of a sudden became worse. Nothing helped except lying down when it would return to normal. I have since gone on oxygen but not all the time. I only use it after exertion (cleaning, cooking) and don't need it sleeping. I am hoping to ween myself off, if I can. Here in Canada the government pays for this service. I am hoping my doctor has some answers for me after my scope in January. Good luck and Merry Christmas!
