Sound-proofing my room

So I have brought my drumkit home, we never practice any more and it's killing me not being able to play! My right foot coordination has gotten really poor and I can't even do some simple things.

Deeply depressing stuff but now I've got my kit here and have more oppurtunity to practise things are looking up! I just need to figure out how to sound-proof my room now though so the neighbours don't complain :p

If anyone has any suggestions for how to do that drop me a line
