I recently started vaping after smoking a pack and a half of cigs daily for 50 years. I have a eGo Twist set at 4.4 and Mini ViVi Nova 2.4. I was wondering if there is a rule of thumb as to how much e juice-15 Mg/Ml I should be using? I started with a 5 fluid oz bottle (15 ml) on Monday. Today is Friday and I have a little over half the bottle left. I am using Vermillion River's "Kentucky Applewood". So is there a norm????......and how do you know how much nic you are inhaling? Is there a way to figure that out? Thanks for any info on this....
