How to deal with a dry throat
Take a steam.
Like using a humidifier, exposing yourself to a steamy environment brings moisture to dry mucus membranes. Use this as an excuse to take a long, hot, steamy shower from time to time.
Another steaming method is to boil a pot of water, remove it from the heat, place a towel over your head, and lean over the steaming pot. Check to make sure the steam isn't too hot first.
