Wow, I never realized there were so many vapers and friends-of-vapers here. Great to see.
Although I hope your going cold turkey succeeds, if it doesn't, I'd also recommend trying ecigs at some point to steer off almost guaranteed health problems. There's actually a crap ton of different devices out there, and most are more powerful than the pinky-sized ones on TV and magazines (those things are mostly for newbies that need something cigarette-sized to hold).
Just a few things to note:
1. Switching to vaping takes work, too. A lot of people, including myself, have gone through tobacco withdrawal symptoms despite initially doubling nicotine intake compared to cigarettes. The cause for that is generally attributed to the additives in cigarettes that make smoking much more addictive than nicotine alone. The sickly taste and smell that you're addicted to can't really be duplicated yet, either. So you have to settle for much cleaner tastes.
2. However, inhaling dozens of burned toxins long known to kill you vs. inhaling one known toxin and a few generally benign chemicals... The odds for this gamble are easy to see. (Feel free to pick my brains on safety issues -- I can't guarantee safety but I could give details on why the odds factually and logically favor the ecigs.)
3. Did I mention the lifestyle improvement? Nothing beats going back in time to an era where you can enjoy inhaling and exhaling stuff indoors, while on the computer, with much milder smells, at work (if you work with good people), in a car with the windows still closed, and without killing your friends/family/coworkers. In fact, I'm vaping on and off as I type this while the wife and baby are asleep in the other room, in peace. If I was still smoking, I'd be outside getting a mosquito bite each minute, then coming back in to hear some blah-blahs about bringing carcinogenic remnants into the house and how I'd be hurting the child if I don't change my clothes, brush my teeth, and wash my hands twice after every smoke.
Two years into steady vaping now after a two-month attempt in 2009 that failed due to super shitty hardware, I'm at a point where vaping nothing but glycerin for days is fine, but it gets boring. A touch of nicotine and food flavoring still makes things a lot better.
