I was a smoker who smoked 2 packs a day for 18 years. I tried to quit by using patches ( still smoked with a patch on), gums ( smoked and chewed gum at the same time), and the drug Wellbutrin ( which made me smoke more), cold turkey, and excerise all to no long term success. About a year ago my husband came home with an e-cig with blueberry flavored liquid and it worked for him. At first I baught a Kanger Evod Pin style e-cig with 24 mg nicotine. I still smoked but cut back by using my e-cig at work and in the car. I broke my Pen style e-cig one day and went to my local vape shop to get a new one. The staff was very helpful in reaching my goal to completely stop. They suggested a rebuild able deck atomizer style tank with a 100 watt Segeli regulated box mod. Within a month I had gone from vaping and smoking to just vaping. I also brought my nicotine level from a 24mg to a 12 mg liquid. Within 3 months I went from 12 mg to 6 mg liquid and for the past 6 months I have went down to a 3 mg. I also have a second vape that has 0 mg of nicotine to mix in through out my day to help me reach my present goal of 0 nicotine by my 40th birthday which is July 4th. Since I have started only using my e-cig I find I can finally run. I can walk my dogs without getting winded, when I catch a cold or flu it isn’t nearly as long a recovery process, but most of all I can breathe. I can take a deep full inhale and exhale with out having brochonial spasms which I haven’t done in a few years. I no longer get Charlie horses in my legs and feet and I can sleep better. I am not by any means a doctor medical professional, but I can see and feel a difference for the positive in my health since I started using my E cig. Other methods of quitting have not worked for me; vaping did, it saved my life. I am no longer a slave to cigarettes.
