Works good for me

I smoked for over 40 years and had to quit a couple years ago because I was having a hard time breathing (can't believe how long it the smoking to have this affect). I still get pretty congested when I wake up so I started popping one of these in the morning and it does a good job of loosening up the flem so I can get rid of it. It's like a lot of things though, some people say it doesn't work and some do. At least it's at a good price and I like how many it has because you can spend a lot more for a lot less.

These are smaller caplet that's easier to swallow. They work quite well. Great price. Will purchase again. I have to use these daily. It's a brand that works (generic) but works better than mucinex. So I'm going to stay with what works. Better price tablet size etc. all the way around. Thank you, Vicki P.

I prefer these short-acting pills to 12 hour power pills. i can control my symptoms more easily %26 effectively. And they work well to loosen mucus %26 get it out of my respiratory system. No drowsiness or noticeable side effects except they may make your urine smell unpleasant.
