I work on my breathing daily. I'm supposed to be 24/7 supplemental oxygen, but I try to go the better part of the day oxygen free. I use a flute, and spirometer daily and a nebulizer 3 times a day with albuterol, and budesonide. Once daily Yupelri. Walking is a big part of helping, along with a stationary bike. I just hope there's new breakthroughs
