dry cough.

somehow in my travels i have developed a rather dry cough. it started saturday before i went to bed and has gotten worse over the course of the day. :( cath has recommended i smear mustard all over my chest!$?# what what what? no way. how gross is that.. i'm thinking nyquil, or some other delicious liquid cough suppressant will be the best for me. does anyone else have a better idea than lubing up my body with condiments?
