I was only using 2-3 mls a day for the first year that I vaped on a Aspire ET-S or some such. Probably less toward the end, because I hadn't realized how badly a Spinner battery can degrade if you charge it twice a day for 13-14 months.
My juice consumption jumped to 6-7 when I got a Nautilus and two mini Aerotanks (possibly more due to the Aero tanks).
Two or three weeks ago I bought a Lemo (V1). I started building at 1.5-1.6 (10W), and now am building about 1.1-1.2, and vaping around 15W, which feels about right to me. I'd say my juice consumption is almost stable at about 7.5 -- 5 ml in the Lemo & another 2-3 in the other tanks.
