You're right, Amalita, you're not out of the woods yet! I really can't say when that point happens, but at this early point in your quit, you need to stay away from other smokers. If that's not possible, then at least ask them not to smoke around you. Just tell them how important it is to you...that it's a life and death matter. Thank God you were strong enough to refuse the cigarette! Those friends are really big time triggers. Oh, I just reread what you wrote and see that you asked for the cigarette, but would you have asked if she hadn't lit up in front of you? I wasn't clear if she actually lit up or if you just asked for one as soon as she walked in the door.
I have to tell you about shortly before I quit. My friend had been quit for 5 years, so I had no qualms about smoking in front of her. Well, one day she asked me for one. I tried to argue her out of it, but she was really adamant about it, so I gave her one. She's been smoking ever since which is about 8 months now. Believe me, I felt terrible and that was one of the reasons I quit, but long story short...I can't stand to be around her even outside, because the smoke makes it hard to breath and my lungs hurt for at least a day. Just try to stay away from smokers as long as you can. Even if it smells horrible, there's still a little part of you that wants to smoke with them.
