well I always check my throat and if there are white circles on your tonsils Yay for strep throat...if not just normal sore throat.
I go fo the halls defense with Vitamin C and drink a crap load of Emergen-C (its 1000% of daily Vitamin C and many other nutrients that help heal ya...its what Opera singers do and they are usually better the next day...but be for-warned...it can keep you WIDE awake if you take too much.
