Jane;
You are almost over the worst of it. The nicodemon is giving it it's best shot to make you fail. But, YOU are stronger.
Remember, if you give in now, you're going to be going through this all over again. You WANT to quit, remember?
What are the main reasons for your quit? Remind yourself. Think of what you are giving yourself, rather than what you are loosing...COPD, lung cancer, emphesima, smelly clothes, hair, yellow teeth.....That's what your loosing!
Breath deeply in and out four cleansing breaths. Then, do something diffrent. Distract yourself. A craving typically lasts 10 minutes. Drink lots of water.
WE're here with you. I'm glad you posted before you puffed!
Keep the quit!
Shalom!
