Greatly helped my cough and congestion

I've always trusted the Mucinex name so I gave this a try . It is the best thing I've found for relief of a cough and chest congestion from a bad cold. Although the cough was not totally eliminated, it was greatly reduced, and I was able to be comfortable and sleep. You may wonder about the taste because a lot of cough medicines taste terrible but this was fine. I didn't have to dread my next dose. There were no side effects from it such as drowsiness Please note : someone over 18 has to sign for this.

Good Stuff

I had Covid and I was unable to get medication for it. So I ordered this and I have to say that it did a pretty good job. I was so congested and had bad aches and pains in my muscles. This really helped with the aches in my muscles and the congestion. I would highly recommend it.

Great product. For mucas, sinus %26 cough without tylenol, so you're not treating fever too soon and of course because acetaminophen decreases glutathione which helps your body clear toxins, including viruses %26 bacteria! So it's a bad idea when your sick. This product lets you separate these things allowing you to add ibuprofen or aspirin if needed.
