Cough
"I was hesitant to take this, but a persistent cough and chronic bronchitis that was well into week 9 left me little choice.  I am typically sensitive to most medications.  Especially stimulants which is why I was so hesitant.  However - I noticed a near immediate suppression of my coughing attacks which would leave me breathless and gasping to the point I was almost vomitting.  It took about 30 mins but I noticed it, and will be taking this again in the future if I have an option to!"
