It's been a year and a half for me (same for my wife). I was smoking almost 2 packs of menthol Swisher Sweets a day. It definitely helps with the "need to do something with your hands thing" I also started at 18 mg and have now dropped down to 12. I use regular tobacco flavor while my wife uses menthol. We tried some of the "sweeter" flavors, but didn't like them. They definitely helped me quit smoking - but the biggest thing (as always when trying to quit) - is that you have to want to do it. Just switching without really wanting to quit isn't the same. I know it's not perfect, but I feel a heck of a lot healthier (and smell better too!) Good luck! Cheers, Doug FWIW, I use the kits and liquid from The Magic Mist. I would also suggest that you not invest a bunch of money in expensive kits at first. They are all different. Try a few and find what you like before investing. I had to try about 5 different brands before I found one I liked.
