I occasionally hit 10ml... but certainly not every day.
I have found a couple of things that contribute heavily to my consumption. Some of those tings are the same things that were a contributing factor to my smoking more when I was a smoker.
Driving - that one is the big one. I often drive a 650 mile round trip by myself. I smoked a lot more while driving distances alone and I vape way more while driving distances alone.
Office work - My job is mostly physical, but I have office days. I am not only allowed to vape indoors but I am also encouraged to and encouraged to share what I know about vaping with my work mates. So, I vape continually when in the office.
Other factors - Low resistance attys go through more juice. Low resistance cartos go through more juice. My 3.7v devices have 1.8 ohm attys and cartos on them and they consume at a higher rate than standard resistance gear does. - My HV kits all consume juice. A 1.5 or 2.0 ohm dual coil cartomizer on 5.0v sucks a lot of juice really fast. -- A 2.5 ohm dual coil attomizer on a 6.0v set up consumes juice at a higher rate than most devices.
Vaping indoors at home. I never smoked indoors -ever - at home. Now I watch tv and vape - read a book and vape - surf the web and vape - etc. If I am not out in the garage working on a car or a tractor, I'm sitting around vaping. Luckily, it's almost branding season. I'll be working a few thousand head of cattle for a few weeks and vaping very little. Also Luckily, summer is almost here again, so I'll be fishing, hiking, tracking, and prospecting in my free time. When my hands are busy, I don't vape much.
Waste - I waste about 3ml a week when I throw out cartos that aren't performing very well any more. I'm too lazy to try to retrieve any juice from a carto that needs to be tossed in the rubbish bin.
Strictly high performance equipment - I'm currently running one of the highest performance attys on a VV Top Fed PV (The VVPV by the way). I have a Cisco hh357 2.0 ohm atty on my VVPV snf and I'm running it somewhere around 4.5v. It seriously consumes juice to make those massive, warm, dense clouds of vapor. I have been consuming about an even 7 ml per day since I got the VVPV and decided to put the hh357 on it.
My average day is around 4ml give or take a bit. But, If I have time on my hands and happen to be carrying some of my high performance gear, I easily double that,
