I have been using so many juices I didn't know how to calculate, so I added up (guessed?) what I used in each bottle and came up with about 60ml in 32 days, so I used about 1.8ml/day. I don't get that, since I have two dual coil ego's with me at all times. I assumed I had been vaping much more.
Same here. I could swear I was going through about 4-5ml a day.... turns out it's much closer to 2!
I'd be saving money if I didn't have to try everything I read about.....

BUT... I'm healthier and loving my new obsession.
