Good responses so far.
I would point out something else to the OP. The degree to which you get nic satiated from vaping depends largely on how much vapor you inhale per unit of time. I started out using the Blucig. It's a good device for its intended niche: for people who were light smokers, or for people who intend to use it while continuing to smoke, as an "out and about" device that they can use in public. However, if you are a hardcore nic addict, honestly I suggest that you try a device with a heaftier battery and a hotter burning atomizer. That will allow you to take in more vapor, and hence more nic, per drag.
I found that with the Blu, I was able to sometimes get high volume individual vapes after fiddling with it, but I could never sustain more than a few in a series. After I received my current hardware, which is a much more heavy duty unit, I vaped it for several hours and got a very intense nicotine buzz. Not only had I never gotten that kind of sensation from the Blu, I had only ever gotten it from my Marlboro's after not smoking for 6-8 hours at a time (like on an airplane), then I would get a very intense buzz with that first cigarette after the long abstinence. That was pretty much the sensation I got with this new device. Of course, I actually overdid it and have scaled back. Anyway, the point being, with a well made, heavy duty device, you get more consistency and hence you have the option of imbibing as much or little as you want, whereas with a lighter unit, you often encounter the limitation of whatever the device is able to deliver at a given time. With the Blu in particular, those batteries are very weak and they start to give very cold, low output vapes well before the blue light even starts blinking to tell you to change out the battery.
I still like the Blu and am keeping it around as a backup and to use in restaurants and bars, but for at home and in office vaping, I suggest you consider a beefier unit. There are loads of good recommendations on this board. I suggest purusing the e-cigarette review forum.
