When I first started vaping, it helped drop me to about 4 analogs a day, but I was also trying to find juices that matched my preferred analogs as well (Camel Light 99s). When the owner of my local B&M found out I was still smoking, he suggested trying a flavor that was something sweet so I gave it a shot and 2 days later, I was analog free. The first week was hard, not because I was craving one, but because I had working my smoking into my daily routine, so with not smoking, I felt like I was forgetting to do something. What did to fix that is I would vape at those times that I was used to smoking and after the first week, everything was fine. My mother-in-law still smokes, she has tried vaping from my device or my husbands device and she just can't do it. She says that she feels her lungs filling up with moisture (she is prone to bronchitis and pneumonia). When she goes out to smoke, my husband and I can smell it and it is horrible.
