third day back and I've already got a cold.

[notsurewhatshappening]

Bustard germs! I wash my hands 653787543 times a day and eat well but get so many colds. Teaching with a sore throat is horrible.
Any tips for supplements or vitamins?

Peppermint tea for the throat, eukalyptos essence drops on your pillow for a good night's sleep with a clear nose and chicken soup made from chicken bones, garlic and whatever vegetables you can throw at it for your immune system.

You have my sympathies.
