I smoked a pack a day for 20 years. I thought the damage was permanent. Day 3 of taking this, I finally started coughing up the black 'junk' stuck in my chest. Gross, but satisfying. My lungs feel lighter than they have in decades.

i struggled with a heavy, congested chest for years. Mucinex dried me out and inhalers made me shaky. I took these drops, and within 48 hours, I finally coughed up the blockage. My chest feels lighter than it has in a decade.
