I went to my doctor this past Thursday with real bad cough, sore throat and feel terrible. She gave an Antibiotics cough syrup Promethazine W/ Codene and told to take Tylenol. Still have bad cough and the cough medicine does not stop the cough I keep myself and my husband awake all night coughing. Got checked for Flu it was negative and chest x-ray No pneumonia. What else to take for cough?
