I’ll start this by saying I was a pack a day smoker for a little over 4 years before switching to E cigs. I had tried nicotine gum, patches, and even Chantix. The gum and the patches didn’t satisfy my cravings, and I’d recommend Chantix to no one. I started with the Blu cigarette-sized E cigs. The amount of vapor they produced just didn’t satisfy the cravings for a real cigarette, and I shortly went back to smoking. A couple months later I did a bit more research on the electronic cigerettes, and ordered a variable voltage(enables me to increase or decrease volume of vapor) e cigarette, called a Provari. The day I got it was the day I quit smoking. It has been 10 months since I smoked a real cigarette and I can’t say I miss them. A large part in the success of my e cig was that my employer was okay with me using it in the break room when on my work breaks. I used to use these breaks to go outside and smoke 2 cigarettes before returning to work. There have been many noticable increases in my health since using e cigs exclusively. After about 2-3 weeks, I could tell my sense of smell was coming back. I hadn’t been able to really smell about anything since my first year of smoking cigarattes, so this was a great feeling. There was also a drastic improvement on my lungs. I found myself with alot more energy, and I also had a noticably greater amount of usable lung capacity. I no longer had a shortness of breath from climbing a flight of stairs, and I also shaved nearly a minute off my mile run.(down to around 6.5 minutes) The reason e cigs actually worked for me when none of the other products on the market could, is because they actually replicate all the motions of smoking a real cigarette. The transition is easy and I believe e cigarettes are a great product. My car no longer has that smoker smell to it, although I use my e cig in the car all the time. I also have no problem using the device in my home, where I have never allowed myself or anyone else to light a real cigarette. Overall, I have nothing but praise for the e cigs. They worked for me, and with absolutely no negative side effects whatsoever as far as I can tell.
