Lynn, I'm mostly a lurker but I have been reading your PJ and I just want to say best wishes for your trip! You've put a lot into this and I know everything will be wonderful for you.
I'm so sorry to hear you're feeling sick - that always happens to me at the worst times, and being run down makes it so much worse. My advice is to drink a ton of water, get rest, and try taking Airborne - it's supposed to stop colds before they happen, and decrease the severity. I thought it was a hoax until I started using it a few months ago, and it has worked for me twice! Anyway, might be worth checking out. hth Good luck!
