I have smoked since i was 5 years old no joke. I have tried quitting with nicotine gum and the candy. i have tried cold turkey, weening my self off and tried tv commercials that claimed you would quite. i have tried snus i am embarrassed to say being a women, but wanted to quite so i was going to try it. I always started back up smoking more then i had before. i was browsing the internet one day looking for way to quite when i ran across the electronic-cigs. So i though what the heck, the first one i got was just a cheapy one, i smoked sometimes on it. Then i decided to try another,and another. I finally got one that worked the best for me, i use between 12mg-24mg of nicotine. i had been smoking for 38 years. And now thanks to the mod type ecigs. i have been without a cig for over a year. I can now sleep with out whizzing. it was so bad that it would wake me up. my heath has improved, life has improved. i would like to thank the person who came up with this idea. it has saved my life thanks so much
