I can't speak for others but I vape slightly less after four months. Sometimes I just put it down for two hours because I don't think of using it. I tend not to chain vape in bed anymore but I'll use it when I wake up in the morning.
I'm not at a point where I'm trying to figure out my unit anymore. I know all my juices, my PVs, I know when they're getting dirty. There's a short of instinct to play with an object you don't understand. Children do it a lot because they don't understand anything.

adults do it when they get a new toy.
