Hope you aren't leaving the house today!
It definitely works! Zicam relieves congestion just as advertised. However, it will cause a constant, unstoppable that lasts for several hours. If you are comfortable with blowing your nose every thirty seconds for several hours to relieve congestion and a slight burning sensation, then it is fine. If you are planning on going somewhere at all or have a sensitive nose, or just hate runny noses, then don't use it.
