I had this for about a year since I had covid - having to clear my throughout every day many times a day. It may have not been as sever was what some of you herehave experienced, but it was still a reduction in my quality of life. I eventually went to see an ENT and he put a tube up my nasal passage and down my throat, and said the mucus looked very dry. He told me to take Rhinaris 3-4 times a day (over-the-counter here in Canada), and drink a lot of water. I did that, and it started to slowly get better. Then I got covid again, and after I got better from the covid, the phlegm, throat-clearing thing came back, even worse, and with a cough this time. I started using the Rhinaris but was a bit lazy about it, only used it once a day or twice when I remembered. After about 2 months, I got a regular cold, and the long covid completely stopped. Then after the cold ended (after about 5 days), it came back, same or a bit worse maybe. Then I started taking the Rhinaris, but diligently, 3-4 times a day, and drinking tons of water. After a week, the phlegm, throat-clearing, and cough completely went away. It's been about a week now, and it's still gone. One other thing I did during the week with the diligent Rhinaris is took an expectorant a few times - not sure if that helped or not but just wanted to let you know exactly what I took to get to this "cure". I hope this works for others, fell really bad for you all, and hope it ends for everyone.
