"Might work, but the taste isn’t worth it"
I bought the liquid version from mucinex.com, the taste was awful. It’s really strong, overly sweet in a weird way, and the aftertaste sticks around way too long. I had to drink water right after every dose just to get it down. Maybe it helps, but for me, the experience of taking it was bad enough that I’d probably choose something else next time.

"Pretty easy to use, but the dosing info could be clearer"
The site was fairly easy to use, and I found what I needed quickly. I was looking it over with my sister, and we both felt like the dosing information was there, but you had to read around a bit to feel totally sure you understood it. Overall not bad at all, just think that part could be made a little simpler.

"I got mine in about four days, which..."
I got mine in about four days, which was quicker than I expected. The box looked fine when it arrived, so no complaints from me.

"Made me feel worse"
I only took one dose and honestly... I felt awful. I got dizzy, nauseous, and super jittery quickly. I really wanted to give it a chance, but I just couldn’t tolerate it at all

"Mucinex has a decent selection..."
Mucinex has a decent selection on their site, and it’s easy to find what I’m looking for. The only downside is that a few things were out of stock when I checked, which was annoying. Overall, it’s fine, I just wish the availability was a little more consistent.

"Helped me out quick"
Support was nice, nice enough for sure. It took a little longer than I expected, but they did help me out quick once they got to it.

"I tried it hoping it would help..."
I tried it hoping it would help with my congestion, but I still felt lousy. Maybe it helped a tiny bit, I’m not sure, but overall I was still all stuffed up and miserable.

"Relief faded almost immediately"
I really wanted this to work, but the relief didn’t last long at all. I noticed it felt decent for maybe a little while, then it just kind of wore off way faster than I expected. I kept checking the time because it seemed like barely any time had passed, and sure enough, it hadn’t. Disappointing.

"Total rip-off for what it is"
I ordered from mucinex.com and felt like a sucker afterward. The same stuff looks cheaper in other places, and the shipping cost just made it worse. For what I paid, this was a overpriced little cash-grab, and I wouldn’t bother buying it this way again.

"Worked quicker than I thought it would"
I was super stuffed up and my chest felt really heavy, so I decided to order mucinex and hoped it would actually do something.

To be honest, it started helping faster than I expected. After a bit, I could breathe easier and my coughing calmed down, which was such a relief.

Overall, I’m happy with it. The site was easy to use, I got what I needed, and the relief came through quicker than I figured it would.
