Push

i think this song is about his heroin addiction he used to have..

You never really wanted it You'll settle for a bit of it We started with a big bang And now it's coming back again

• i think here he's saying that it started out that he only wanted to try it maybe to fit in or just for something to do and it didn't really matter, he just did it in his spare time and then all of a sudden he started craving it and depending on it basically.

It'll wear you down and wear you down

• i guess it's basically self explanitory. it's something that makes you seem happier and happier everytime you take it when in reality, if you don't have it, you're just getting more and more depressed.

You didn't think you'd feel it all but you were wrong about it

• i think he's saying that he tried it once and figured there'd be no harm in it since it was his first time but he got hooked right away?...

Using like it's going out of style maybe just a little while

• i think he's saying how he used it soo much, everyday, maybe even several times a day almost as if the next day there'd be no way to get anymore.

This'll be the last time everytime's a last time

• very self explanitory. he kept telling himself he was going to stop, going to quit, just one more time.. but one last time turned into a second time and then a third and so on...

and as the last lines say, he regrets ever touching it because it probably screwed his whole life up..
