Recently quit smoking waking w noc asthma attacks-coughing up clear bubbly phlegm-otherwise young healthy active female. COPD? Cause for alarm?

Unlikely. COPD takes years to develop so this is probably not that. This is probably combination of allergies and poorly controlled asthma. I suggest follow up with your doctor so that you get proper inhalers and perhaps pulmonary function tests to gauge severity of asthma. Congrats on stopping smoking!
