Take Mucinex And Feel Better Faster

Mucinex is our go to for colds, sinus, congestion, etc. It works faster than some other brands we've tried through the years. Many times, one dose is all it takes! I don't remember us taking it for more than 2 days except for the two times we had the flu.. IF Mucinex does not work, then it's time to see a doctor! So far that has not happened! . The only thing we don't like is the size of the pill when we have heavy congestion.

Mucinex

I have bad sinus problems. It cuts the throat drainage. During bad allergy season, I take two a day (one in the morning and one 12 hours later)
