You don't describe your "breathless-ness" enough to compare with other stories here but perhaps your Doc may consider nebulizer treatments for more coverage throughout the day. Those meds would include Duoneb and a stereoid for inhalation as well.

Some people are also on Daliresp or azithromycin because of the anti-inflammatory properties. Reducing the inflammation can result in better breathing.

Azithromycin and prednisolone don't seem to relieve my breathlessness
