interesting question amigo. but mentally, you are just making it easier for you to justify continued drug use in the long run. every time you say stop to yourself, then you use, its easier to use the next time. youre basically bullshitting yourself, you are weakening your own defense mechanism against yourself, your conscience. keep it up, and youll notice you had a fallout with the little angel on your shoulder, and your new best friend is that little devil..... the only reason you used, is because you justified using. at first, it takes a while to justify use, so you fought over using for a good long while, then gave in... pretty soon, your justification will be "ill stop tomorrow".... trust me, i know from experience. i bullshitted myself for an entire year before i finally got over using heroin.. now i mentally dont like it as much as i used to. .... LEARN TO HATE IT. or youll just learn to love it more
