I was a pack-a-day smoker for 40 years. Some days more, but averaged one pack a day for the last few years. Never less. I got my first disposable e-cigarette kit December 26, 2012. I quickly (within a week) moved up to mods and began buying custom made e-juice. I started with 36MG of nicotine. I vaped at that level for about 30 days and then went to 24 mg. By 120 days I was getting 16 mg strength on the nicotine level. I am now mixing my own e-juices and begin with a base that is 12MG nicotine. By the time I mix in my flavorings and menthol, the solution is running about 9 MG strength on the nicotine. So I have gone from 36 mg to 9 mg in 5 months. In the first week of using an e-cig I smoked 4 analog cigarettes. I have not had a single cigarette or any tobacco product since December 30, 2012. A pack a day for 40 years to ZERO in less than a week. Unbelievable. I had tried a few cessation products such as nicotine gum and the patch, but always gave up within a week or two of attempting to quit that way. And even then I was only able to cut my smoking by about half even while using those products. I went to counseling for a very short while, but the truth was I was not ready to quit. I really had no intention of quitting smoking even when I got my first e-cig…I was just trying to please my daughter who had given it to me. After 4-5 days I could not even stand to smoke a real cigarette. I sleep better, I smell better, and I feel better overall being tobacco free. I can taste much more subtle foods and flavors. I seem to just be a little more energetic and able to maintain a longer concentration level in my work. Oddly enough I have had absolutely no cravings for tobacco or any desire to purchase cigarettes. It honestly surprised me how quickly I was able to walk away from a 40 year habit. I realize e-cigs are not a perfect solution…but the alternative was so much worse! I have experienced nothing negative about this transition from tobacco to e-cig products. Initially I did not save a bunch of money due to the fact that I spent almost 2 months trying different systems and e-juice flavors in an attempt to find the set up that worked for me. I was spending about $240/month on cigarettes. I now spend about $60/month on mixing supplies and cartomizers. I see that being reduced slightly as time goes on.
