This song is about how hard it is to stop using drugs According to The Heroin Diaries: A Year in the Life of a Shattered Rock Star this song is about when Niki Sixx starts to use heroin ,however it's a failure according to reach the target(ending the addiction) but it doesn't mean that it's a total waste and every one may make mistakes and it's alright because you may start again and you may win this time.
Don't give up, it takes awhile
I have seen this look before
And it's alright, you're not alone
If you don't love this anymore
