I find putting my pv just out of reach helps with non stop vaping. If I feel the urge, I'll grab it and take a few hits, and put it down. Part of being smokers, we have this hand/mouth habit to break, if the pv is in my hand, I'll keep vaping.
Another thing that helps me, is dripping. I'll drip 3 drops into the attie, and when I need to drip more, I put it down.
