@britelite - Good 4 months for me. I didnt work for 3 month and 4th went to work for 4 hrs only. My o2 was dropping pretty bad, so i had supplm o2, bad sob just to walk around the house. I couldnt walk our dog down the street (i weightlift at baseline), i did nebulizer every 3-4 hrs to help with sob and still mostky sat on sofa just trying to breathe. I was also on two rounds of diff abx and two rounds of 2 diff steroids. ( these were alternated over few weeks) I was told due to asthma it would take few months. Was hard to believe at that time that it will ever get better, but looking back now, it indeed took some time. At some point, my md rxed tiotropium bromide (Spiriva in liquid) to nebulize together with albuterol.
Look into nebulizing/speak to md instead of using inhaler/puffer, it makes quite a difference. For a reference i picked Phylips Respironics InnoSpire Go (can only buy wity rx). Its quiet and fast then what i was given through insurance - noisy and very slow compressor plug in machine.
I read above that you also had cardiac issues, need to be vigillant, have mds exclude that sob and wheezing not carduac related as well.
All the best,
