Yes they are expensive but really do the trick!
Our family has been battling Influenza A this season and could not seem to get over it. ChatGPT recommended this and to drink lots of water with it. It has finally broken up this dry tight cough and chest pain and I think we might finally be getting better. It's cheaper than most prescription copays and it works!!

I can't believe I lived this long without it.
Okay, I'm 70 and this is the first time I ever tried Mucinex. I was so impressed! Why had no one told me?! I had one of those summer colds that spend a week in your head and another week in your chest and keep you from that weekend trip with the girls. I ordered up anything I thought might shorten my misery, Mucinex being one. Finally! I could cough up and out the horrid junk in my lungs. I asked my daughter, “Why did I not know how great this works?!” She said she'd been using it for years; she didn't know I wasn't aware. Well, I'll never be without it in my medicine chest again!

I take these as soon as i start to feel congestion in my chest to keep it from turning into bronchitis. Take these and drink plenty of water and it keeps the congestion loose it's easier to expell it.
