I started vaping a year or so ago with the idea of gradually quitting smoking. I found that I could not inhale the vapor, it felt like it was tearing my lungs out, I tried many juices and strengths, but just couldn't inhale, so I went back to smoking (& coughing, wheezing, & chest gurgling) full time. One day (while having a coughing fit) I decided to quit smoking and got out my vaping stuff, patches, hypnosis tapes, and determination, and did it. After the first day I found the I could inhale the vapor very comfortably and really enjoy vaping. It has been over 3 weeks, and I am convinced that I can stay off the butts forever. I still listen to the hypnosis tapes from time to time, and found that I was OD'ing on nicotine with the patches so pitched them, now I am vaping full time. After 66 years of smoking (I'm 78 and started at 13) I am off butts for good. So if you are like me and can't inhale vapor while smoking, you might want to give it a try.
