Karma bit me! Four days after I posted my message, I was hit by an exacerbation driven by pollen, allergies, working outdoors (stupidly) unmasked and asthma.

Six days later, after countless nebs including several at 4 am, addition of budosenide (steroid) nebs, hours of coughing to the point of sore ribs, and closing myself into the double HEPA-filtered house, I am beginning to feel I have turned the corner.

Apparently 7% saline and good airway clearance have kept me healthy enough to be able to avoid another course of oral steroids and antibiotics. But they are in the cupboard if I need them! This is why we never say "cured."
