Attack your congestion
Mucinex time-release guaifenesin tablets are amazing! The guaifenesin ingredient thins mucus and so relieves your sinus and chest congestion. This particular product only has 600 mg so I take 2 if my congestion is really bad. There is also another formulation with 1200 mg. And there are cheaper off-brand versions that work just as well. Just make sure they actually are identical.

Mucinex Works for Upper Respiratory Film and COPD
I have COPD and I have alot of phlegm in my lungs and Upper Respiratory System. Without Mucinex I would suffer every single Day. Mucinex (with 8-12 oz of Water) breaks up Phlegm and Loosens it so it is a product that I have counted on for Decades. I highly recommend anyone with COPD who has issues with Phlegm production to buy the product and drink a Bottle of Water with the Pillow. Mucinex (with water) breaks up the phlegm so that it does not Congest your Lungs and Upper Respiratory System. I take a Mucinex with a Bottle of Water about 30 Minutes before my Bedtime because without it I will not have a restful sleep. HIGHLY RECOMMEND. Have used it for years with Zero side effects. Thank you Mucinex!

Because of my upper respiratory issues, this Mucinex was recommended by my respiratory surgeon. And I tell you, it has truly been a Godsend! Every morning, the mucus is coming up and I'm able to get rid of it, thank God!
