Excellent product just expensive.
The Guafenesin really tackles the mucus at the bottom of my lungs on an extended assault and the Dextromethorphan finishes it off!

It Works for me
It helps loosen the phlegm and controls the coughing, I don't hear the rattling of the mucus in my chest. I will continue to use it and would recommend it to anyone with excess mucus issues.
