I've essentially quit analogs and ecigs.
That said, i still puff on both at times.
If you've reduced your intake to a level that's almost zero, it's not a big deal, unless you're dealing with a life threatening disease.
Sometimes I'll have 3 analogs in a night, or even 10. Then I'll go 2 weeks without a single one. I might puff on an ecig a few times in the evening, or I might not puff on one for days.
The important thing is that you get your intake down to near zero, and don't fall back into bad habits. If you have a cig, oh well. Just don't wake up the next morning and light one up. The same can be said about ecigs. They're also adictive, and if you can use them to sidestep analogs, that's great. If you use ecigs for the nicotine and don't reduce your level of intake, then it's still better. If you use ecigs to reduce your overall nicotine intake, and also drastically reduce your analog smoking, then you're on the right path.
/Quitting cold turkey is easy. You just have to quit again, every time you relapse. The more times you quit, the less of a hold it has on you. It's giving up and thinking that you failed yourself, that will cause failure.
