Katika,
I just quit smoking in the spring. I know what you're going threw it is extremely difficult!
I had been a yo yo smoker for 10 years, it started just occasionally, like when I was drinking or when I was with my sister and it just progressed from there.
Every time I got stressed out, I'd bum one and then wind up buying a pack.

What ya have to remember is you can never again think you can have just 1 because you will go right back to it. I try to avoid certain people and situations that trigger me.
I still crave one once in a while, the last time I had one though, it tasted nasty, so I guess it does get better.
