Why are we always addicted to something bad for us?

Chocs.
Too much of em is bad for us, but we're still addicted to them anyway.

Alcohol.
Too much of alcohol makes us puke, but we still put ourselves through and through wid drinking anyway.

Smoking.
Once a smoker becomes a smoker, there's hardly any turning back.

Drugs.
We all know how hard it is for druggies to quit.

I know my addiction, and I don't know why I am putting myself through with it. I love it, and can't live without it, but at the same time, its not entirely the best thing for me at the moment.

Am I abusing myself? Do I get off the pain and hurt that comes with it? This so reminds me of one episode of SATC. Rings a bell, Tina??

Sigh, I dont know.
