"Popcorn lung or bust!" I finally quit smoking after about 20 attempts last year, after having smoked about 10 years, 1-2 packs a day, 3 on occasion. I'd tried everything. Patches, gum, e-cigarettes, etc. The e-cigs didn't help me at all... in fact they extended the very same problematic habits (fingers wanting something to do while I had a drink in the other hand, primarily). Gum was good for situations where lack of nicotine was removing my capacity to concentrate. What finally worked was taking a month away from any familiar drinking/smoking environment and any work commitments. I would recommend quitting your job, changing your environment and just going cold for a month or two to successfully quit smoking. Don't rely on products, they're just feeding the same addition. Most people who successfully quit apparently fail to quit a lot of times (8-12?), though not as many as me. So I'm something of an expert. ;)
