I am personally only vaping in my free time, which basically means that I won't vape at work or if I go to places where it might not be appropriate as well.
I am not really dependent on it as I will sometimes also go for several days without vaping at all, therefor it's not really a problem for me as I also don't experience any cravings or such.
But on a free day, when I've got nothing really to do, I'll basically vape throughout the whole day getting through roughly 3ml-10ml of liquid.
