Smoked for years. Quitting cold turkey was the most effective way of quitting for me in the past. However, I'd find that after a week, a month, or a year something stressful would happen ( it always does) , and I'd start smoking again. I tried e cigarettes a few years back, however the device wa expensive for something that was just going to break after a few months. Last summer, I found a brand that makes disposables. They are the equivalent of 1.25 packs and sell for $8 at local pharmacies. Using the e cigarettes, I found myself smoking less and less until the point where I just forgot about it. I had actually planned on getting a reusable/rechargeable kit and refills, but at this point it seems a waste of money. I keep the e cigarettes around for an especially stressful day, or when friends who smoke call and want to get together, otherwise, I don't smoke anymore.
