I struggled with quitting smoking for 14 years. Surprises me that 14 is the number as I had never thought about how long I had smoked. I am not a smoker any longer. I tried horrible cigalike e cigarettes in Nov of 2013. Aweful product that I now know I only used due to availability. I received my personal vaporizor for Christmas from my father. Due to ejuice not being readily available locally I did not use it until February 2014. I have not smoked combustible cigarettes since I began vaping. Prior to vaping I would wake up light headed from wheezing all night. Many mornings my oxygen level was so low that I was very irritable. This was not a good thing for me or my family. I feel unintelligent that I continued to smoke even though smoking was obviously killing me. Since switching to vaping I breath great and my quality of life has improved dramatically.
