After reading your post aubergine, about how you found out about e-cigs, i have to chime in here once more..
I'm only 27, but i have been been smoking from 16 till about June of last year.. So in those 9-10 years i slowly began to feel it's effects.. I too could see how i couldn't hardly run as i once did before i started smoking.. I always felt low on energy, and just very bad some days.. I even would often get very sick and would vomit very nasty black stuff.. 8-o
I tried the patch which only made me itch like crazy, and even the gum which kinda tasty nasty.. I still had the mental urge too smoke, to have something in my hand, too see the smoke as i exhale..
I first saw a kiosk at my local mall that said electronic cigarette.. At first i was very dismissive.. "Ha, how can a ciggy be electronic?!" Was my first thought.. "You have to light it to smoke it!?" Then as i struggled to quit more and more, i figured, what the heck, I'll google it.. Well guess what i found when i first googled?!
I found all of Leafords you tube videos!! Yep, and i watched all of them all the time for about a week..

Thats when i stumbled across ECF.. I began reading about them here as well.. But i really have to give a bunch of credit to Leaford.. Seriously, without his vids, and actually seeing someone explain and use the PV's in a video, i doubt i would of tried them myself..
Once i got my first kit i was blown away.. It really did feel like i was smoking!? I thought wow, this is going to work!! After about a few days of using the PV i totally quit analogs completely.. (well not having the cash to buy them helped too, and the cost of a pack of them..

)
About a month after getting off of analog's, I too started to notice my breathing changing.. I could breath deeper.. I also started to get more energy back.. And darn it if i just don't feel good all the time now.. It's almost like it's a crime too feel this good..
Since then i have followed Leaford's blog, etc.. I finally had the money to switch over and try the VK.. I have only heard good things about it.. I really wanted to give it a try as I'm always searching for something better..

That and i believe the prices have come down as well which helped me a ton.. (and the discounts! wow, thanks for those Steve!! Every dollar saved helps too!!

)
So now i sit here and wait for my new VK to comes to me in the mail.. (hopefully today.. USPS says it was sorted in Atlanta yesterday!!)
But the hardest thing is to come is waiting for those batteries to charge!! Ohh, i get to sit and drool over my VK for 8 hours while the batteries charge..

I guess i should of gotten the PT too, but that will come later.. I'll just have to use my other PV till the batteries charge..
