I tried the provari and it was amazing. I knew I wanted it but couldn't justify the $400 price tag until I looked at the math. Basically spending $20 a week on cigs, 3 packs only so I said if I buy the provari, I'll stop buying cigs and would basically save me money over the long run. I break even at 20 weeks. For me it was a matter of economics. Plus it saved my life
