I used to smoke an ounce of Golden Virginia a day.
There's two things you need to know:
1. It's something that created it's own need. You weren't born needing a cigarette, you didn't need one until you had your second one.
2. Everyone that smokes looks absolutely stupid. Seriously. All smokers look pissed off when they're smoking and they think no-one's looking at them, because deep down they all know how stupid it makes them look.
Stopped five years ago, and haven't touched one since.
Take it easy, you can too.
Incidentally, about a month after I stopped I pulled this girl who smoked. We went back to hers and ended up in bed. She stuck her smoke flavoured fingers in herself, then in my mouth, and not a word of a lie, I nearly threw up on her.
Cigarettes are disgusting. Really, you have nothing to lose.
