Are you nebulizing saline 3 or 7% after your albuterol treatment? If so, the airway clearance following the neb treatments should help you bring up the mucous and hopefully improve your breathing over time. I’m about to turn 74 and am on the big 3 since January. My ID doctor has spaced the meds out during the day and so far I have been able to tolerate them. My symptoms prior were fatigue, cough and weight loss. Hope this helps.
