Nothing beats Mucinex for congestion from colds and flu. I have been sick for three days with sinus pressure, runny nose, fever, and all over aches and pains. I was taking several name brand cold and flu medicines and they helped a little but then a friend of mine brought me some Mucinex. One tablet later, I felt like Me again. It is a bit more expensive than some of the others, but you get what you pay for and it is definately worth it.
