Smoked for 30 years, on average 1 pack a day. Tried to quit may times with the use of patches and also nicotine gum. The patches made the application area sensitive in addition to soreness of muscles under the patch, so I was back to smoking. The Nicotine gum resolved my smoking for 6 months, but I was always chewing the gum and it started to make my jaw joints sore. So I was back to smoking. 4 months ago I purchased a rather higher end electronic cigarette power source device and assorted atomizers etc… I have completely quit smoking. No more coughing, no more dizziness after that first cigarette of the day. Summary: I will never smoke again. Vaping taste better, I use less nicotine, almost none at this point in time. I feel great. My breathing is back to normal. I sleep on my back again. I sleep without waking in the middle of the night. I have not gained any weight, because I use flavored vegetable glycerin and it satisfies my snacking needs. Need I say anymore. It works as an cessation device without a doubt. It is also a fun hobby tinkering with the equipment and mixing your own juices. Vaping will save your life!
