Wanting to be a non-smoker is a good place to begin.

I no cleared my PM's but jbug might still have the one I sent her with my tips. I quit 3/1/05 after 30+ years.

It's wonderful to not have my hair, clothes, breath smell horrid.
It's very freeing--the habit takes a lot of money, energy, and time.

Things that helped me:
Think of it as becoming a non-smoker--gaining something rather than losing something.
I realized that smoking was how I handled anxiety and especially peaks in anxiety, so I had to find other ways to react to that. Crisis is the most common reason a non-smoker returns to smoking.
Realizing that the first 2 weeks will be the hardest. Sometimes it's just good to know what we face.
Cut down before quitting.
Drink a lot of water. I had about a cup every hour at work, less at home.
Get the rest you need. Very important to feel well rested and have the energy needed to go through this.
Time the cravings. They come .. and then they go. They are limited and they don't have to be acted upon. We can just experience them, note what we're feeling, and how long they last. (also a good time for a glass or bottle of water to remember how fresh we want our mouths to feel). Knowing a craving will be over in minutes helps get through it.
The cravings will lessen in frequency and duration.
For now, avoid places and activities where you smoked. I liked to sit outside and smoke while doing crossword puzzles. Smoking was a part of that routine and I had to disrupt the whole routine for a while.
At the same time, increase time spent in places (bubble bath!) and activities (swimming, crocheting) that you don't associate with smoking.
At the same time, add a healthy food or two to your diet.
When I went out for breaks at work with my smoker friends (I would have had to avoid them if their smoking made me want to smoke too), I would stand with my arms folded across my chest--because not having something to do with my hands drove me nuts. Might have looked funny, but it worked.
I also ate blow-pop lollipops. (I liked the stale ones I could chew on before I even got to the gum to chew!)

You'll find thngs that help you. Make note of them to remember if you need them during a particularly hard time, and as a reminder that you have been able to get through hard times before and you can do it again.

Good luck to you!! You can do it
