The advise above is great! One thing to add....buy some Vick’s Vapor Rub. I kept the stuff everywhere, it’s like magic.
I would rub it under my nose and even went as far as putting a tiny bit on my tounge, I lived, lol. I also kept the Vick’s inhaler around for fast help. Dunno why, but the smell of it it took my crave away almost instantly. You still need to do the reading. Once you understand WHY your craving the nicotine so bad...you will fight it that much harder!
Get he Vick’s though...it will help , less stress 
Prepare well, do your homework and you'll discover you have less to fear because you'll understand more about the nature of this addiction, what's in store, and have the tools necessary to overcome it. It's just a skill to be learned. And just like any skill it simply takes study, hard work and perseverance. Will the process be unpleasant? Yes. Most new things take us out of our comfort zone and make us feel like a fish out of water. Will you survive it? Yes. Because each day you remain smoke free will be another day under your belt of experience and will give you confidence.
The Quitting Journey is all about ATTITUDE. Take it as a challenge, as something that's going to empower you in ways you've never discovered, as a growth process - and you'll move faster through the unpleasant parts with long strides. Focus on the negatives, the missing, the longing - and you'll grind your way through slowly inch by inch. Stick around. Knowledge is your friend here. And so are we.
I smoked like a chimney the night before my quit. But I had made a total commitment. Once you've said, "I WILL, no matter what," you're halfway home. The rest is all about 'time.'
Stay positive, stay motivated and bring along your sense of humor. It a great tool to have in your quit kit. Smoking isn't the end of your world - it's the beginning of it.
