Cough and Nasal Congestion
"After having a sinus infection for three days, I went to the immediate care center: they recommended Mucinex D and a saline nasal wash.  I felt relief from the two combined methods that I started that morning. However, after taking the second dose of Mucinex D that night, I found that I only had a couple of hours of interrupted sleep. Now on my second night, while  the congestion is much better, I am still not sleepy - even after hardly sleeping the night before.  I checked the Internet and found this site - apparently  this is not uncommon. Tomorrow, I will only use it during the day and rely on the saline nasal wash more."
