When I started with mods that weren't ego-sticks I was doing 2-5ml a day. Now, with 20-30-50w mods, I'm finding that creeping up. Part of it is my current ADV, but it's also all the extra wattage and dripping. I think I'm now at 6-10 ml a day at 6mg. During working hours, I'm still right around 3-5. After work though, when I'm dripping at home...
