scratchy throat and stuffy nose relief, fast?

Rachh asked:

okay I was on vacation all week and my allergies started to kick in. first it was just a sore throat but then my nose was completely clogged. I took a couple allergy pills because today I have to sing at my cousins graduation party. And my throat is still scratchy while my nose is not really that stuffy , i can blow it and what not. but i feel really clogged. i took a claritin and had a cup of hot tea, but still not much luck, i still sound scratchy and i’m guessing this is because of a nasal drip and what not. any remedies or tips that will get me better, fast?!
