About how many Mls would you say you vape in a single day?

I started vaping a few months ago. I use a [5ml Aspire Atlantis](http://i.imgur.com/2xpHlZ4.jpg) tank and go through about 2.5ml of it in a night, which is when I mostly vape. I've never heard how much someone else vapes so I have nothing to compare this to, and I've also heard that the Atlantis goes through juice quicker than others, so maybe that's part of it.
