Mucinex D
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'd taken something years before with the same ingredients as Mucinex that helped immensely and thought that the money was worth it. I've been on it a week, every twelve hours, and haven'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't rest AND with the added jitters and insomnia I feel worse than before. I wish I hadn't taken it to begin with."
