I have the same problem. While my cough is better when infection has cleared, I still have daily violent coughing, sometimes in the middle of the night. I faithfully nebulizing 2x daily which greatly hells tame the beast. I also sometimes take Benzonate(?) to help cough as well as lozenges in public. If your cough gets worse than your “normal” or you are feeling unwell get sputum sample and talk to your doc. Good luck!
