Used to be completely addicted to smoking.
Think I started when I was... hmm.. 15? I smoked about half a pack a day and it went up to almost a pack a day.
But I quit smoking a year and some months ago and I'm feeling great.
Do I get urges to smoke? Sure, but it's not something I ever plan on doing again.
And it does make you stink. I didn't realize it of course when I was smoking, but BOY! I notice it now when a smoker goes by.
And I've had a few drinks in the past and probably will in the future.
I don't drink regularly or anything. The last time I had a drink was when I went to Las Vegas (few months ago). I had 2 drinks the entire time I was there. They were pretty tasty too

heh
They were those fruity slushie things.
One came in a nice orange glass from the Flamingo Hotel/Casino. The orange stuff on the glass came off though when I stuck it in the washer

That drink was REALLY good. You couldn't taste the alcohol in it at all.
And the other drink came in this really tall (bout 2feet tall) blue plastic cup from a mexican restraunt in the NY NY hotel/casino.
I can't stand the actual taste or smell of liquor though. As soon as I smell it it makes me ill.
And now that I'm a bit older and know better, I don't like getting drunk. Little buzzed is ok, but that's it.
