I have same, in CT. It has taken 3 different Rx to get at it and I’m still coughing at night! When I first found out I had it, I wasn’t even coughing! If this is you, pay attention to your ears... if they start to hurt when you blow your nose you’ll know if what you are taking is or is not doing the trick. Ok, maybe not, everyone is different but it’s a kicker if you have what I have! May take more than on Rx. Take care of yourself FRiend!
If you have ceiling fans, could the problem in part be from dust accumulation.
I’m so sorry for you. You have my prayers, sweet GizzyGirl. I’m pretty sure, mine is just from letting myself get rundown over the recent passing of my cherished DrO and not eating properly. I’m also down over 25 pounds.... I bought KFC, milk and ice cream...LOL.
