I typically go through about 2.5 - 3 ml a day.... sometimes more on the weekends. 

Usually vape around 4 ml a day @ 12 mg. Finally got into DIY. It's not as expensive to start up and honestly it's a lot easier than I thought. I wish I had have gotten into it a long time ago.
I spent around 80 bucks for everything needed to last for months (for my wife and I). Just a tip though, it's easy to go crazy picking out flavors since they are so cheap. Be prepared to wind up not using some of them.
Not sure why I thought 'Hickory' would be a good flavor, but I can't bring myself to vape it.
If you decide to get into DIY, I can tell you a few things I've learned not to do, but it really pretty easy.
the places that sell the DIY supplies all have storage bottles...there are glass & plastic....personally i use the plastic ones (they are graded) for storing and never had any probs...store in a dark semi cool (room temp) area....i use a portable plastic shelf with lids and have the lids covered to block out light...every section is filled...![]()
