I eat so many cough drops that my stomach starts to feel queasy.
But uhm, hmm. If your throat is scratchy or phlegmmy, and you aren't opposed to soda, I find the fizzier sodas to be very good at clearing throats. Grape sodas and lemon limes seem to work best for me, for whatever reason, although most things carbonated might help.
If your head is feeling all stuffy and head-coldy, a hot shower might help. Whenever I'm particularly stuffy or my head is just feeling very UGHH, I sit in the bathroom with a book and turn the shower on full blast. I let the steam accumulate and sit there for 10-20 minutes depending and then turn off the shower. Pop in a cough drop and sit until the steam is mostly gone before you leave. Usually it clears my sinuses for a good few hours.
Especially sore throat, I usually drink said carbonated beverage to clear it and then suck on some ice. I know it sounds weird, but sometimes the pure ice cold melting water soothes a lot more than a cough drop does, although I've had some times where my throat has been so torn up that cough drops feel like heaven in a little candy like package.
And... soup. The steam clears sinuses, and something about soup just makes me feel better.
That said cold solutions are different for everybody. I don't take medicines because they don't really help.
Oh, and gargling with salty water also helps clear throats. I've rarely done it, because I'm horrible at gargling, but it does work most of the time. And wiping your face off with a hot towel can wash away some of the sleepiness that comes with colds.
