I am a #3. For me the hand-to-mouth thing is just as, if not more, of my addiction. But very addicted to nicotine. I quit all nicotine for 6 months then went back to smoking, but began to develop a really bad reaction to cigarettes. I would get... sorry if this is TMI... but I began to get instant ........ just a few puffs into a cigarette, along with bad stomach pain and all-over itching that is common for me with allergies. Then it would all subside over about 20 minutes or so. This started happening every time I had a cigarette, and I even tried different brands. This sounds wild, but I swear to god. But even with that, I couldn't stay away completely. With an ecig I do not have any of those symptoms, and it has toned down my addiction a bit. I do not bring my ecigarette into the bedroom as a general thing, when I am lying in bed I am relaxed and focused on going to sleep instead of nic-fitting. My husband recently switched from smoking (mostly a pipe, sometimes cigarettes) and I have seen a nice change in him. Vaping is a lot more casual, and he no longer gets strong urges I have noticed. He used to HAVE to step outside periodically, whenever he was awake, and it would interfere with him going to sleep sometimes I think. I was the same way, but it is neat to see the change in someone else. I think with vaping you are able to puff here and there to keep kind of a steady nicotine level, rather than big dips and rises like with tobacco use, which cause bad cravings and withdrawal. I seem to recall a study that indicates that as well.
