Cough and Nasal Congestion
"Started taking this a week ago because of terrible congestion in my head and chest along with RX Tessalon Perles. I&#039;d taken something years before with the same ingredients as Mucinex that helped immensely and thought that the money was worth it. I&#039;ve been on it a week, every twelve hours, and haven&#039;t been able to sleep more than five hours a night (about 4am after taking it at midnight until 9 am.) I still have terrible congestion with heavy thick mucus. Just finally realized about thirty minutes ago that the Mucinex is the only change. I can&#039;t rest AND with the added jitters and insomnia I feel worse than before. I wish I hadn&#039;t taken it to begin with."
