I've been hearing amazing testimony from the Internet, friends and family about this stuff called Zicam which is a gel sprayed into the nose to prevent the severe symptoms of the cold and even reduce its length. You take it when you feel the symptoms coming on, and the gel helps prevent the cold germs from multiplying in the nose. Yesterday, I started feeling the stuffiness and sore throat, and today, it's slightly worse. I predict that Thursday would be my worst day, but I bought Zicam this afternoon, and I'm hoping that Thursday will be a good day for me. So has anyone else tried this stuff? did it work?
