cough and nasal congestion
"I read the reviews on Mucinex and was a little concerned but I was also desperate. For 2 months I had a thick post nasal drip that would cause me to constantly cough, especially at night. I had to sleep sitting up in my chair in the living room. I was wheezing, runny nose, coughing up tons of mucus or clearing my throat from it. I took one tablet at 8 am and another tablet at 8 pm. OMG I can clearly breathe with no wheezing or congestion or mucus getting in my way. I slept through the night and when I woke up my nasal passages and throat were clear. "
