My Oldest was up all night coughing and before I could get to the store the next day, my free sample of Mucinex arrived in the mail. She drank some and right away I noticed less congestion, sneezing and coughing. She finally slept well and so did I.
I like to keep this on hand since it's always 3 in the morning when I wish I had it. It's early this year and I was caught off guard. Praise God that I got it anyway!
