I’m sorry, but it’s now 9 months and I’ve been through the same. My answer is ‘No’, and I have tried it all.

It was diagnosed for me by ENT as chronic neurogenic cough with throat clear. Steroid injections and mild antidepressant helped temporarily. Stopped the antidepressant after six months and still have the problem. It is so annoying.

I too had the post nasal drip but it's gone now. I had something (maybe COVID) in November 2022 but it was very brief, like 2 days. Then I developed a coughing spell that lasted about 2 month with constant mucus in my throat. The FlowNas provided a little relief but nothing else worked. Then I talked to a friend and he said he had the same thing and he uses Sudafed Sinus Congestion so I bought some and started using it. About a month later, the mucus was gone. It's nearly been two months now since I've been mucus free. Maybe the warmer weather helped but I'm pretty active as well. I do alot of exercise like hiking and biking.
