I quit smoking three months ago. Cold turkey. I got a cold and only smoked half of my last cigarette-- it tasted like poo. I was never a heavy smoker, and not addicted to the nicotine, so I didn't get any physical withdrawal. (Sorry, I can't help you there!)
You could think of the cigarettes as a bad relationship. And you're breaking up with them. You're tired of them making your house, your clothes, your car smell bad. They made you stand outside in just barely above freezing weather in the rain for a few puffs. You keep throwing more and more of YOUR HARD EARNED MONEY at them and they're so ungrateful. They never told you that you look good, or complimented your cooking, or made you feel special.
But, you say, they helped me when I was stressed. Well, not exactly. They made you stressed when you went without them for so long. And then you had to have another one to bring your stress level back to normal. They're the evil ******* that abuses you and your wallet and your lungs but makes you feel so bad for leaving but they really want to control you and your money.
And, you know, kill you and your husband and your kids, but you already knew that.
One thing that's helped me is
http://www.quitmeter.com. When you quit cigarettes you put in your quit date, number of cigarettes smoked per day, and cost per pack. It'll keep track of how long it's been since you've quit, how many cigarettes you haven't smoked, and how much money you've saved. It's a wonderful motivator-- "I've come this far, I don't want to ruin all that now!"
...sorry if this came off as preachy or whatever. It's past my bedtime.
