I was absolutely shocked (and so were my family and friends) when e-cigs TOTALLY replaced my regular smokes from day one on. What's more, it was just sheer luck because I didn't order e-cigs originally with the intent or goal of quiting at all. Just to give me some "inside" smoking time as I stopped smoking inside my house 15 years ago. That didn't cause me to "cut down" my "smoking" - just learned to be better friends with things like rain, snow, hurricanes or whatever!
Truly, the most important thing I ordered (by luck I guess) along with my first " standard KIT" order was the USB to PC e-cig battery and I wouldn't have quit cold turkey if it wasn't for this device. As a 2+pack/day person, I managed to drain those "4" regular batteries I originally ordered within hours! But the USB to PC e-cig battery is like the Everyready Bunny. It doesn't lose it's charge! Just keeps plugging on full strength as long as PC is on, and that was important to keep the satisfaction level high. The extra higher strength cartomizers I ordered helped too like others suggest. But realistically, I needed both -- the constantly and fully charged USB passthrough battery and the higher strength cartomizers (and plenty of them) to get that "satisfied" feeling you're referring to - especially in the beginning.
Just a note: My USB to PC passthrough battery does NOT work in the wall charger that came in my kit. The forums have advice from experienced users on how to get them to work in ways other than just with the PC. It's a voltage thing. You'll still be teathered to a charging unit just not the PC. Good advice throughout the forums on this for beginners like us making the switch.
Two months now analog free, loving my e-cigs, and I'm OFF my $400/mo (retail price) lung drugs for COPD and I feel soooooooooo good, able to do things I haven't done in years. No wonder the drug companies hate e-cigs. Makes you kind of wonder just what their true motives really are!
Congrats on your successes so far. It doesn't matter how long it takes -- only that you, at your own pace, make the switch. IT'S SO WORTH IT!
