I smoked a pack of Marlboro Reds a day for 23 years. My spouse was a 3 pack a day Camel Wides smoker for over 20 years as well. My spouse wanted to quit smoking and I didn’t. I loved smoking. I agreed to quit almost a month ago and because I know myself and my addiction level, I knew that the patch, gum, or pill would not be effective. I decided that I would try the ecigarette as a tool or crutch if you will (I normally refer to it as tobacco replacement therapy), in helping me to give up smoking. I have been using an ego vaporizer because they are refillable, I can choose the liquid I put in it, I can choose the nicotine level, I can choose the flavor and it gives me that throat hit that I have been conditioned by cigarettes to enjoy. I use varying mgs of nicotine liquid. Sometimes I use 24 mgs, sometimes 18 mgs, sometimes 16 mgs. The latter is really not enough, so I mix it with a higher mg liquid. I am down to 1 analog cigarette a day which is amazing to me, as I didn’t think I could live without my cigarettes. The ecig made my attempt possible and more successful than I ever thought especially at this early point in my attempt to quit. It mimics all the things I loved about smoking (hand-to-mouth, throat hit, vapor cloud) without all the icky things (other chemicals, awful smell, etc.) about smoking. I can not stress enough that without the ecig, I would never have been able to cut down or eventually stop analogs all together. This product is literally a life saver.
