I had smoked since I was around the age of 9-10. Yes hard to believe. I had quit cold turkey, I had used the patch and the gum at different periods of time, and finally I tried Champix. Oh yes the miracle drug! However it caused me to have stomach problems that I have never been able to get rid of. Did I quit with it? Yes for 3 weeks each time, but when I couldn’t endure the pain and nausea any more, I went back to smoking. Then in the spring of 2011 I happened upon the Electronic cigarette. Much to my surprise after using it I didn’t want to smoke. It took me about 4 weeks to completely remove regular cigarettes from my life. I use mostly eGo type batteries with clearomizers. As well I use a larger battery called a mod. I had been diagnosed with COPD in 2007, was told by the respitory therapist that I would be on oxygen without a doubt in about 5 years maximum. My lung capacity was in bad shape. I had been on advair, a puffer, and various other lung improvement medications. Once I put the regular cigarettes down in 2011 I had not used my puffer once, until two months ago I got a severe cold and it was the first time I had picked the darn thing up. I had to renew my prescription as it was out of date and didn’t have any solution left. I have not used advair once! MORALE of the story: If these things had been around 30 years ago, I would not have acquired COPD, and I would not be sitting here typing out this story! —- My husband had NO desire to quit smoking, NONE! After trying mine he said, I think I would rather use that then a cigarette. Needless to say, he has not smoked in 2 years now either! Thank you E-Cigs for saving our lives! AND rescuing me from a oxygen bottle!
