    Helps keep my chest open and easier breathing.

    I have chronic Asthma, which makes me wake up with a cruddy chest every morning. I take one at bedtime. These expectorant pills help me get a clear chest easily after I get up. Without them I cough for a few hours. Then I can exercise easier too.

    Key is to never let it sit in your mouth, get a drink before you get ready to take it but yes great relief!

    Love the larger sizes

    I am someone who takes these twice daily and being able to get the larger quantities is totally worth it!
