just call me phlemy.

I have been babbling on, at top speed, for the past three days. Explaining concepts, software utility and methods of use to a group of eager students. My throat is raw, my voice is nasally, and I have the most uncomfortable stuffed sinus feeling that sits at the back of my throat and makes talking a chore. Is it just me or does everyone get the phlegmy, stuffed, nasally, frog stuck in the back of their throat feeling when they jabber consistently for days at a time?
