I've noticed a lot of the things you all have mentioned, but one of the biggest positives to strike me is the realization that I am a drug addict. Yep, that's right. When I smoked, I knew I was addicted, and they were bad for me, but they were so easy to obtain and the ritual so cemented in my life that ... well, I accepted it. Vaping, with all it's intricacies, it's ups and downs, it has really opened my eyes to just HOW much of an addict I am. I am far more conscious of my intake, of my impulses. It has made me a more mature person, I am less likely to say '.... it' and do something, instead I think things out.
Not sure if this makes a whole lot of sense, it's kind of hard to put into words, but vaping has literally made me a better person. Perhaps it's something to do with better focus like some of you have mentioned, but I really do think it has more to do with the constant battle with making vaping work for me (less so anymore, thanks to better gear and places like ECF and other online haunts) and the fear of falling back into the analog habit. I am aware of the hungry little monster inside of me, and I'm learning how to shut the evil ....... up now and then.
