allergic rhinitis
"The taste is bad but it works!!! If you get the technique right it shouldn't go down the back of the throat, google how to do this. When I take it I have some mints standing by just in case, this helps mask the terrible taste. I have suffered from sinusitis/allergies for years, which completely block my nose. After about 4 days of using this twice a day this started working. Now my nose is completely clear and I take one pump in each nostril every day as a preventative. It is expensive, but it's the only long-term spray I've found. In Aus I pay about $55 for it."
