For Cough "Actually, I was using Mucinex to control a nagging nighttime cough. Although I had extreme pain in my ankles and legs EVERY SINGLE DAY, I never dreamed that Mucinex would have any effect in helping that. I took a dose of the Mucinex FastMax just before I went to bed, and WOW, no cough AND no leg pain at all that night, at last, I was pain-free! I know it had to be the Mucinex because absolutely nothing else had made a difference! I will keep some on hand to use from now on. I hope this helps someone else also. Thank you."

For Fibromyalgia "I had a terrible experience with Mucinex. I followed the protocol for just over 1 month, hoping to feel some relief, but I felt really heavy, like I had a bad flu, and had worse pain. I think most people are experiencing relief, so give it a shot; it just didn't help me."

For Cough "I had the flu, and night coughing was keeping the family from sleeping. I tried everything! This worked the first night. I noticed it made my throat feel dry and sore. Drink plenty of water."

For Cough "I just tried the Mucinex pill (12 hours) for the second time. Both times, it made me cough more and harder. The coughing is now painful and less productive. I am throwing it away."
