Best cough med around

This is the best cough medicine for help with my seasonal allergies and asthma. Once the drainage gets in my chest it takes a lot to get it out but this is the only medicine that is over the counter that works for me. I like it in liquid form because it seems to work faster than pills.

What A Relief !

I personally caught a real nasty flu . The congestion and sore muscles I had were overwhelming. I was coughing non-stop . I was prescribed medication for the infection. I needed something for the congestion , sore muscles, and coughing . As usual, I jumped online and went directly to Walmart. I saw Mucinex Fast Max . The description of this medicine is exactly what I needed. I had relief on the first dose . I could feel the warmth of the syrup lining my throat with comfort. My coughing stopped. My head wasn't hurting like before. I was really surprised how quick Mucinex relieved my symptoms . The product is reasonably priced . The taste isn't that great, but the quick results are worth everything.
