LA trip cancelled

I'm not coming down to LA tomorrow, for those of you who I was going to see. I did the no-nyquil experiment last night to see if my cold/cough/plague has improved to the point where I can sleep through the night without drugs and it failed. I was up coughing until I caved and took the drugs. Stupidly, I feel alright, a little low energy, but not as bad as I have felt. I just can't seem to kick this cough and don't want to get on another flight and dry out my sinuses again. Plus I just saw all my profs a week ago and don't have anything new to give them yet.
