Cough and Nasal Congestion
"I developed a serious cold with immense pressure fom my sinuses on my eyes and head. The first day at 7am I took two Mucinex-D ( Clears nasal/sinus congestion, Thins and loosens mucus) in the morning and sure enough within hours my nasal passages cleared and there was constant flow of mucus throughout the day.  I was sneezing all through the day. Again took two at 7pm in the evening same result.  I slept for maybe 3 hours and then was up all night until 6am. All night I was constantly blowing my nose and sneezing. The next morning I took two.  Maybe tonight I will not take any. The only discomfort I notice is my left nostril that is the one most clogged is constantly itchy like I want to sneeze all the time and of course the insomnia."
