Once a day, 4-5 times a week. I up this to daily if I get any kind of congestion, virus, etc. And twice a day during an exacerbation. This "slacker" schedule came about after my last pulmo visit, where my lungs looked their best in 5 years, with the consent of my doc. It also coincided with a change in my asthma meds that reduced those symptoms to almost nothing.
