I am just about 24hours into my e-cig experience and haven't had an analog in as many hours! Well, actually I am about a week into me e-cig trip. Last week I bought a SmokeStick(RN4081) at a local smoke shop at the time it seemed like buying something that I could buy locally was the best solution. I got it home and charged up the battery and took a drag only to have it leak in my mouth. Which actually ended up being a good thing because that is how I found ECF. Multiple days of research later, I ordered a 510 and ECOpure 20mg liquid from a fairly close supplier, I'm in Seattle, they ship from Boise. That was Monday night and my stuff arrived yesterday. So far so good! If I have the urge to smoke I just take a drag off the e-cig. After smoking for 20 years it's quite refreshing and I already feel like I can smell things better. Like, my sweatshirt smells like smoke. LOL got wash out that combustion! So, 20 years combusting from a pack/day at the beginning down to 10 analogs/day and no desire to "smoke." I have found that I only need to take a drag or two at about the same frequency that I used to smoke entire analogs(American Spirit Light Organics). Just wanted to share my initial experience and say thanks to ECF and it's informative members!
