I quit 50 pounds ago, but I don't regret it for a minute. Had stopped several times before, but always went back. This time, I used the patch and Zyban (Welbutrin). I enjoyed smoking, but knew it was time to quit for my health. Still hung out downwind from the smokers to catch a whiff, but only outside - never in a closed space. As time passed, I found myself standing farther and farther away. 6 months and I wasn't there anymore. Been over 12 years now and my MD says he can find no evidence that I ever smoked (though I did for 25+ years). Can't say I don't still get the urge, but not very often anymore.
I would like to find the money I'm supposed to be saving though.
