E-cigarette.
I LOVED smoking, and I loved my morning routine and other routines that included smoking. It seemed a way to have the best of both worlds.
With e-cigarettes, you're "smoking" water vapor and the nicotine you get is totally dependent on the level you buy. I currently have 16mg tobacco flavored cartridges and they work fine (you can go down to zero if you want). You get the nicotine, you get to still go through the motions of smoking (oral fixation), but you don't get all of the bad chemicals that come with burning tobacco.
I have two brands. The first is Fifty-One Duo, which I got from a mall kiosk. The second, which I got online after doing a lot of research, is a ProSmoke. Personally, I like the Fifty-One better overall even though the vapor in the ProSmoke tastes better/sweeter. Do NOT get the ones you see in a gas station or a smoke shop. I have yet to hear anything positive about them.
It took me a full 24 hours to get used to it and I had to switch my mind to believing I WAS smoking. After that, I stopped craving real cigarettes. Some people step down gradually, but I figured the cold turkey was the best way or me. After 3-4 days, I tried smoking a real cigarette, and I didn't much care for it. I did have a couple of "fits," so I got a couple cigars and keep them around for those rare occasions where I do want one.
That's just my 2 cents.
Before anyone brings it up, I have heard several warnings about nicotine and hormones. I have yet to find any credible literature that shows a bad link between the two, and to be honest most people who talk bad about smoking use "nicotine" as the catch-all for everything bad about tobacco. The fact they never mention that tar is what stains and carbon monoxide causes blood problems is telling that they need to do some reading themselves.
If anyone DOES have any empirical studies that show negative effects of nicotine on hormones or increased dangers, please let me know.
