I'm another one that has to see that cloud of vapor to feel satisfied. It never made much sense to me, but I quit trying to figure it out. I just vape on.
I easily go through 6ml per day. Usually more. I've even gone through 12ml in a day. I vape almost non-stop most days, but it depends on what I'm doing. I can be busy doing something and notice that I haven't picked up my PV in 3 hours and I'm not craving it either. Seems strange, but then I probably always have been a bit strange. I know that when I smoked, I could not have made it over an hour without a smoke or I would have been pulling my hair out. I know because I tried it when I'd try to quit smoking. I just couldn't do it until I started vaping.
Absolutely less nic!!! The nic level doesn't have much to do with my vaping anymore. I vape a lot of 0mg and some 6mg. The coffee flavor I LOVE doesn't come that low, so I get it in 11mg. I don't vape a lot of it because I use it as my "desert" or my "treat".
I don't know if it's age or vaping, but I don't seem to get nearly as stressed as I used to. I wonder if it has to do with not having to worry about when or where I can get my next smoke. Maybe because I can vape anytime, anywhere I want to, it keeps me a lot calmer.
