In the last few months, I have developed severe post-nasal drip due to allergies. I tried several different supplements, none of which did much. The Neti Pot brought some relief, but it would only last an hour or so. It got to the point where it felt like my breathing was impaired because of how badly the phlegm was blocking the back of my throat, which was very anxiety-inducing (in addition to being uncomfortable, annoying, and gross).
I saw that someone mentioned Cayenne in a cocktail on EC. I tried it and it brought IMMEDIATE relief. It was like a miracle. Now, I take a Cayenne Pepper capsule about three times a day and it has wiped out about 90% of the phlegm build up behind my nose.
Previously, I was waking up several times throughout the night to clear my throat, now I don't wake up at all. Just be sure to eat when you take the capsule, otherwise, it will do a number on your stomach.
