Blergh. I have come down with a cold - it started on Saturday, so it pretty effectively squashed the whole weekend for me. So, in honor of my current state, I'll link you to The Chorister's suggestions for what to do when you're sick. I've only heard of echinacea - anyone else have experience with olive leaf extract or bee propolis? (Hat tip to the Choralnet blog, btw, for pointing me at this entry.)
Or I could always take my own advice.
