Giving it a go

All right lotsa personal stuff coming up.About 2 weeks ago I get a phone call telling me my brother is in the hospital with stage 3 lung cancer.He was a lot older than me and I wasn't in contact with him much because he had his own family out of state.So this news kinda hit me in the face like a sledgehammer. I hear that it's pretty much dire and hopeless and they're just trying to make him comfortable.I was at work at the time,stop smoking, and as soon as I got off my phone,smoking cessation, i crushed my pack and threw it away.I'm 25 and started smoking around 13. And I just decided to quit smoking cold turkey. Mind over matter.Now I'm usually the kind of person whom after making a decision, is set in stone. I went home after work and later that nightstole one from my girlfriend. That was my last whole cigarette in one sitting.I'm still buying them for her and she says "if you can make it a month i'll quit". But anyways.I feel my quitting is on the right track. I haven't bought my own pack since, but I've been taking one from my girlfriend every couple days.During the day at work and even on my days off I don't crave at all really. But i crave about 3 puffs every night.So a cigarette is lasting me like 3-4 days.I just need to know what I can do to get myself over this last hump. If i can stop a pack+ a day almost instantly, I knowI can beat this. I WANT to. But the late night craving is driving me nuts. I know it has a lot to do with the fact my girlfriend is still smoking and I really hope she will quit like she said.Sadly my brother passed on 12-2-09. He died in his sleep. He had smoked for about 35 years.I miss him and I want to do this for myself and for him.
