Lingering bronchial cough is still here, however--
I feel MUCH much better.
Went for a bike ride today, walked around the city yesterday, cleaned the entire apartment today, and vocally, although I still feel a bit fatigued after one hour of practice, the one hour is definitely as it should be in my voice.
Doesn't feel like I have a huge head cold anymore.
Repertoire for upcoming audition feels really good again (finally), and other general repertoire for upcoming operas/concerts feels equally 'in line'.
