Long (3-6 second) pulls, inhale, don't hold it in lungs and slowly through nose/mouth with a couple rings for fun. I vape "constantly" I suppose, but it's not like smoking analogues. I will take a few pulls, put it down for 5 minutes, and take a few more. Sure, sometimes I'll sit and power-puff for 10-20 minutes straight on occasion, but not nearly as much as when I first started.
My first.....4 weeks-ish I was definitely chaining, cooking 4-6mL a day easily, making myself woozy to the point of needing to lie down a few minutes. Once it passed I'd get up and start again. Working from home has advantages. I'm not sure when it happened, but around 7 weeks in I noticed I was forgetting to vape, sometimes for an hour+ stretch. I've since "naturally" reduced to 2-3mL/day. It's odd because I don't feel like I'm vaping less, but the numbers don't lie.
You may want to look into WTA (whole tobacco alkaloid) juices, there's more to tobacco than just nicotine, and some people find that WTA is the difference. I've not had experience with it so can't personally vouch for it, just know what I've read here and from meetups.
Another thing to keep in mind: Ecig nicotine delivery is different than cigarettes, the uptake is generally through the mucous membranes in mouth/sinuses. These are less efficient than lungs and it's slower to absorb, upwards of 20 minutes. Ecigs also lack those fancy chemicals they add to damage/shred the lungs to increase nicotine uptake. That may just be some scare thing I was told, but they definitely alter the tobacco to increase its efficiency.
