CL, I hope you feel better! Make sure to drink a lot of water.
My 2 cents about Airborne:
It does not work. It's been studied and the company was subsequently issued to pay close to
$24 million in a recent settlement for false advertising. Also, more of a concern about Airborne:
people end up taking too many of them and this is dangerous as there is a TON of Vitamin A in them, which can cause substantial damage to your liver. There was a recent publication in Nature
If it does work... it's most likely placebo effect.
