Good luck ladies,
I highly recommend Quitnet.com just like lewysgal suggested. You can plug in your quit date, the amount you smoke and the price of your cigs and it starts to run a tally on how many cigarettes you didn't smoke, days of your life saved and money saved. I quit almost 3 years ago and I still check in with them periodically. The people on the boards are very helpful and committed to helping anyone who posts.
I did gain a bunch of weight afterwards but it was a slow gain over a year's time - it made the decision to quit all the more difficult - BUT it was the right one to do. I still miss the cigarettes sometimes tho I really notice the smell now and it's pretty stinky to me. It's nice not to be coughing and clearing your throat all the time. Nicer still not to sit and fidget in places, waiting till you can escape and go have a smoke.
I didn't want to eat candy so my "trick" for the first few months was to cut a straw in half and I'd hold it or take a "drag" when I'd get cravings. That would get me past the oral fixation and it's zero calories. They also tell you to take a few deep breaths when a craving hits. I also starting drinking lots of water.
You metabolism will take a tiny bump downwards once you quit the nicotine but you can counter that by adding some exercise into your day. March in place until a craving passes. Take the stairs and notice how you're getting less out of breath.
Exercising got better once I had more stamina as my lungs healed.
Mark down all the reasons you wanted to quit so you can read them again if you've feeling a weak moment. Remember - a craving only lasts for 3 minutes on average. Those first few weeks they may come every 10 minutes but they will get farther apart as time goes on. Stay strong and you can do this.
The other thing I'd suggest is for the first year at least, every week take the money you would have normally spent on cigarettes and put it into a jar. I wish I had done that - would have had over $6,000 by now. It adds up.
Wishing you the best of luck...
