Cough
"My Dr. prescribes this for me every fall/winter.  I get a cold, it turns into bronchitis and then I can&#039;t sleep or function normally due to the horrible coughing.  I take it about an hour before I go to bed and I sleep like a baby, no coughing and wake up refreshed and ready to go.  Side effect is I feel a little groggy until around 11 am but that&#039;s not a big deal for me when you aren&#039;t coughing and able to sleep."
