I don't understand.

So, why, if I took Nyquil, am I still coughing? In addition to that, shouldn't I be out cold by now? With all that alcohol? Maybe I should consider bed. It is still early, but the Nyquil will kick in eventually, and probably make me sleepy before bed time anyhow. Guess I will turn in early, hope I fall asleep faster so I won't cough as much. The music is over and there's not much else to do anyhow.
