When I first started vaping, I bought bottles of 18mg and 0mg juice. My intention was to start at 18, then go down to 9 (by mixing the 18 and 0), and then finally go to 0mgs. Well, the first 3 days at 18mg were so rough that I decided to heck with it, I might as well just go straight to 0mgs and get all the suffering over with at once. I am now 4 months analog and nicotine free.
It's strange how my habits have changed. The only time i vape is when I'm in a particular chair in the family room or at my computer. If I'm anywhere else other than these two locations, I don't even think about it or the fact that I was ever a smoker.
