cough and nasal congestion
"Followed directions & took 2x Mucinex D 1200mg at 930PM.  Decided to pick this up after bring sick & out of work for 5 days.  I was really tired & dozed off at 1130PM.  Its 330AM, I can't sleep... I'm wide awake with an extra dry mouth, swelling of the tongue, slight nausea, tossing & turning (anxiety?), tingling/weakness in my arms.  Most of my cold symptoms are gone(amazingly!), but I can't shake these side effects right now & am wondering exactly when I'll be able to sleep!  I would NOT recommend taking this at night time, & if you are going to try this stuff to start with just 1 pill."
