Hack... the cough!

Does anyone know what it's like to be under the covers... dying to go to sleep but can't because you have a dry cough??? Several doses of Tussin, tea and cough drops later... still a dry cough. It's nearly 4 AM and i'm up feeling my chest vibrate to the nasty sounds phlegm makes. Yummy. ...That and my eyes are twitching. What would Joe Pesci do at a time like this? Hmmm...
