Well guess what My room mate too snored at one time. so what i did was, I had this aluminium Jar of water with a spoon which i use to keep by my side every night, just in case i needed to drink some water in the night.

So every time my room mate snores, I make a small noise with the spoon and the jar.

Now he gave up snoring , seriously this helped. But now I no longer need to make any noise.
