Cough and Nasal Congestion
"My mom caught the cold I have just beaten and it affected her much worse. After consulting a doctor/friend she recommended trying Mucinex 12 hour. At around 7 PM,  she took to 600 mg tablets. She reported being awake all night with heart palpitations, jitters, and a  pounding headache. She also threw up in the middle the night and feels nauseous again this morning. The cough is coming back as the Mucinex wears off.  The drug worked  to stop the coughing but the side effects can be hard on some."
