Cough and Nasal Congestion
"Allergies   pink eye = terrible congestion and a sore throat from all the eye drops.  I took Mucinex D to ease the congestion a bit.  It has thinned the mucus significantly, however my stomach is very gassy and unsettled; and my heart is also racing!  I haven&#039;t taken my temperature, but I feel a little feverish.  Like many of you I was not able sleep last night.  I will probably halve the dose tomorrow. But all in all it&#039;s worth it.  I can breath and that&#039;s probably the most important thing."
