@kmacky my pulmonologist gave me samples of Trelegy for long Covid cough...really bad kept me up nights...I noticed a difference day one!
My pulmonologist put a sticker on the samples.
Rinse, gargle with mouthwash, brush teeth after Trelegy dosage.
This process worked, and the antiseptic in the mouthwash, I think, makes a difference.
Good luck to you.
