I had smoked for 20 years and was a 1.5 to 2 packs a day user I had tried disposable e-cigarettes on and off for almost 2 years and they in no way helped get me off the real thing. I had also tried patches in the past to the same affect. I then decided I had to quite no matter what. At the start of May I picked up a refilliable/reuseable/rechargable e-cigarette from Halo. I also bought some patches (strongest they make). I used patches and the e-cigarette for a week. The patch helped the cravings but not all the way, the E-cig filled in the gap most of the time (I had about 1 real cig a day. I’d light it, take a puff then put it out, relight as needed through the day). During this time I noticed the cravings were less and less after the 1st couple days I was only switching the patch every 36-48 hours instead of the directed 24 hours So I stopped using the patch and used the E-cig a little more the 2nd week, and I noticed I was not smoking all of my allotted real cig each day When the 3rd week rolled around I had stopped smoking any real cig (removed them all from the house), but I was using the e-cig a lot more. Since that 3rd week I’ve only been using the E-Cig but I have greatly reduced how much I use the e-cig. This reduction was not planed or attempted it is just what I’ve noticed over time. Also I started with 24mg NIC level now I’m at 12mg. So in the last 2 months on the E-cig I dropped my NIC level by half and I’m also only using half the liquid I was when I started.
