If nicotine isn't addictive then whatever is addictive in a cigarette is also present in vaping. 40+ years of 2-3 PAD and I tried many, many times to quit and failed. When quitting cold turkey I would get a feeling like something was crawling out of me from the inside. Very similar to the other addictions I had and overcame 20+ years ago. Throughout the years I've tried patches, gum and the deadly prescription med that's advertised on TV all the time and none of them worked for me. I won't even go into my horror story with the prescription poison. I've been clean and sober for over 20 years now but would always fail when I tried to quit smoking. 5-6 years ago I bought my first e-cig and immediately quit smoking without the withdrawal symptoms I had on previous attempts to quit cigarettes. I would always wind up back on cigarettes due to getting frustrated with the leaky tanks that were the only thing available other than the cigalikes which didn't do it for me. This time around (50 some days ago) I bought better hardware and have been smoke free ever since and down to 6, 3 and sometimes 0 mg of nic. I'm chain vaping but I'm not smoking cigarettes. If I go more than a couple hours without vaping (except while sleeping) I start getting the feeling that something is crawling out of me from the inside. As soon as I start vaping my 6mg within a couple minutes the feeling subsides. This time around I'm also making my own e-liquid and my plan is to slowly decrease the nic.
