What's the difference between hydrating the bronchial airways with a nebulizer and an APV? A 40+ year smoker off analogs for 2 months, I get in a steamy shower and I cough up clear phlegm. I vape excessively and I cough up clear phlegm. I go to the steam room at the spa ( OK only twice because my employer offered free visits), I cough up clear phlegm. Why should I pay for an albuteraol prescription when just hydrating my lungs does the same thing?
