"Sick since Thanksgiving (now Dec. 16) and finally went to immediate care clinic. Put off going to a doctor because never thought there was anything that could be done for a cough as persistent as this: wrong. Be sure to share all your medications, prescribed and natural (like sambuscus). This is helping my unproductive cough be productive, when I do cough. It does lessen its frequency. It also prevents it from turning into something worse if I had nothing and just kept coughing. Plus, coughing spreads the germs, so by lessening it you stop spreading it to others. I had no nightmares and had normal just great sleep. I do not write on these sites ever, but thought this ah-ha might help."
