I have been analog free for 1yr 3 mos. I had to quit because of pregnancy. I bought the e-cig because I returned to work and it is a high stress job. Most of my co-workers smoke. the urges came back and were horribly intense. I bought the 901 and have had it for 2 days and it takes care of the urges wonderfully so far, and the last 2 days at work were incredibly horribly stressful! Keep up with it and I believe anyone could go completely analog free. It depends on how bad you want to be rid of them.
