Not everyone has a physical addiction to nicotine…some people have an emotional addiction, if you will, for some type of comforting repetative motion. Like puffing on an ecig, or biting their nails or sucking their thumb. I don’t fully understand the hand to mouth need, but I have it. With the ecig, I am not forced to smoke nicotine to simply satisy that hand to mouth need and here is the kicker…for the first time in 40 years, I am not being forced to ingest nicotine to satisfy an emotional need! I am 61 years old and have smoked heavily, 1-2 packs a day, since 1972. I quit smoking all nicotine/tobacco products two years ago. I used an ecig to accomplish this successfully, over a 5-6 week period. I tapered off the nicotine, begining at 10 and dropped 2 points each week, then completely eliminated the nicotine altogether, never to have it added again. I continue to puff on the nicotine free ecig machine as needed. I continue to have the hand to mouth need, something similar to nail biting. However, no nicotine consumption or second hand emissions is required! To quit smoking, you have to want to stop…even with the aides (the patch, the gum, etc.) the reason for that is…the aides rarely work unless you already have extraordinary well established self-control. I didn’t smoke because I was addicted to nicotine. Everyone told me I was addicted to nicotine, but they really did not know that for a fact. They just assumed that after 40 years of smoking 1-2 packs per day, I must be addicted to nicotine. As it turned out, I started the ecig at 10 units, an extremely LOW number for units of nicotine to begin with, for a 40 year smoker of 1-2 packs a day. I had absolutely no discomfort whatsoever. No need to adjust the level of units of nicotine. No stress, no withdrawal symptoms at all. I was always completely satisfied with 10 units or 8 units or 6 units, it made no difference to me physically. When I elimated the nicotine altogether…I was completely satisfied with just puffing on a flavored vapor. How could that be? I smoked for 40 years like a smoke stack!! Over the years my doctor’s talked me out of using Wellbutrin with Chantix or the patch or even the Nic gum, because I did not want to stop smoking, but no one cared that I did not want to for emotional reasons!! They insisted, I had to want to quit and that I was physically addicted, I had to admit to it (like an alcoholic), for the aides to work. Bunk and more Bunk. I don’t bite my nails anymore since I started using an ecig either!!! Longest, healthiest nails in the world, today… Karen Riner
