Cough
"Have been prescribed this med twice before. First two times worked like magic. Just swept the urge to cough away. This time, years later, same story. After 8 days of continuous wracking coughs, and 20-hours a day in bed, gave up on OTC-DM tablets and went for better help. After 1 perle, the coughing has subsided.  No side effects. Bliss."
