They finally had a product that (for me), actually relieved a stuffy nose. No other so-called cold remedies ever worked for me (comtrex, the old "good" niquil, the new not-so-good niquil, tylenol cold, etc). It would clear my breathing for HOURS. I am positive this stuff actually got rid of the cold pretty quickly too.
Now the FDA says that just using it one time can make you permanently lose your sense of smell. 130 cases reported so far.
