I've been vaping a few years now, and the thing pretty much NEVER leaves my hand. I do remember getting headaches when I first started, and I hear from many that I've helped switch to vaping that they initially feel like they are od'ing. I'm not entirely sure what to speculate about that....I've definitely reduced my nic consumption as I've gone along, from 36 to 24 to 18, and now I vape 12mg mostly with the odd grab for the 18 when I feel I need it. I'm personally very sure that even in the 24mg range you're getting far less nic than smoking analogs, but that's certainly not coming from any official testing or anything. I generally hear, and remember from my own experience, that the headaches last a few days or weeks and then life as a non-smoker gets awesome. I wonder if the headaches are actually our body telling us it wants more nicotine?! I get the exact same headache if I haven't had a coffee by 11am. Anyway, yes for sure, like my pack o smokes once was, my case of vape stuff goes with me everywhere and I absolutely NEVER forget where I put it down! lol
Well thats good to know that it lasts two weeks, the headaches, because i'm still getting mine, been about 9 days now.
