Anyone coughing like crazy?

Jessica
Hi all! 👋🏼 
I have had a cough for the last 8 weeks; it's mostly unproductive but it sounds like a smokers cough. It comes from deep in my chest. I've been through two bottles of Robitussin and a z pack from my OB but nothing has helped. 
Is anyone else experiencing this? Any remedies? I am starting to get concerned.
