I was a smoker for 20 years starting when I was 15. I started using an e-cig on 5/04/2013 and stopped smoking cigarettes that day all together. I use a vamo mod and started with 24mg nicotine and I have been able to decrease the nicotine to 12mg. I am now able to breath like normal, I sleep better, food tastes and smells all back now. I must say it has even improved my driving not having to worry about flicking ashes out of my window while I drive. the best part of using the e-cig instead of smoking is being able to keep up with my son and knowing I will be around longer for him.
