I have a sore throat, feel a cold coming on. is there anything i can do or take to prevent the cold from happening?

Probably not: Unfortunately, if you're about to get a cold, then you're likely to catch one. To date nothing that i know of can stop a cold. Prevention is always stressed such as washing your hands, alcohol based hand sanitizers, flu shot, plenty rest, less sugar consumption, staying away from sick individuals, stress management, and nasal lavages to keep nose moist. All help, but don't prevent or cure. G-luk.
