Hello, I have read and even downloaded that XLS calculation macro and cannot figure out how I would create an e-juice that would be most comparable to what I smoke in analog form. I smoke carlton cigarettes that claim to be .1 mg of nicotine per cigarette, I smoke between 3/4 a pack and a pack a day. So even worse case scenario I am only consuming 2 mg a day of nictotine, and if you take into account the fact that I might get a bit more, lets say 4mg per day. How could I mix an e-juice up so that I can get approximately the same level of nicotine that I get in a analog smoke currently? I am assuming it would be easiest to buy 15ml e-juice flavored how I want it with NO nicotine and then buy the flavorless ones with nicotine in it, then put the smallest amount into that. What amount I have NO idea.
