I have been using inhalers for asthma and then COPD for some years now. In January, 2021, I was prescribed a nebulizer to help with the albuterol and saline inhalation to help keep my lungs clear. Come to find out I have been doing things backwards. I should be using the nebulizer to open my airways, and then use the inhalers for optimum penetration. With gray hairs come wisdom.
