Cough and Nasal Congestion
"I tend to get a sinus infection at least twice a year. The only thing that helps me during this time is Musinex D. However, after the first time taking it and not being able to sleep I decided to take one pill every 6 hours instead of 2 pills every 12. Taking it this way allows me to breath and still be able to sleep at night. For me it is a miracle worker."
