I don't know yet! I also wonder if the goiter is affecting my sleep -- almost everyone who hears me sleep thinks I have apnea, and now I wonder if the goiter is making it harder for me to breathe when I lie down. Could be!

But I think the major cause of the coughing is definitely the pneumonia. I've been on huge doses of antibiotics for three and a half days now (thu night, fri, sat, sun) and already am coughing a little less. I slept over five hours straight this morning! Wheeeee!
