Clear up congestion easily and quickly

[This review was collected as part of a promotion.] I am a fan of mucinex—I often feel confested and stuffy. This over the counter medicine helped me feel better quickly!

I bought this product just a few days ago due to having a major chest cold. I felt relief in a matter of hours. I am a very skeptical person and this product truly is helping me, thank you!

Quick relief

[This review was collected as part of a promotion.] I'm surprised this product worked as well as it did. I've been congested for a few days and tried it out. It cleared up the congestion and loosed the phlegm quickly.

Works wonders

[This review was collected as part of a promotion.] This is the best stuff on the market. It might knock you out for a while, but you wake up feeling like a champ.

Works hard like I do…

I can take this every morning and night during the worst pollen times and it helps keep me breathing freely without worrying about getting pneumonia (yes I get my pneumonia vaccine too). Mucinex is the only thing I need besides my antihistamine. I recommend it to everyone who has allergies and that horrible irritating cough.

Quick relief

[This review was collected as part of a promotion.] Worked quickly. Was only able to use it once, since I was only congested for just a day.
