It's been almost 2 months for me. The first 2 weeks I was still supplementing analogs occasionally, then I had houseguests for a week, and my mom came out too, so I had a hard steep curve to deal with. When I switched I was vaping nonstop low vanilla from TW. I'm sure if I had a stronger juice I wouldn't have vaped so often, well I can't say for certain. I still get the urge for an analog at times, but I just vape more. I'm glad I have switched over. I can't say it's been less expensive, but I'm sure as time goes on, the costs of e-cigs and the paraphernalia will be less than what the costs of analogs will be. Congrats to everyone. This is has been a great switch for me.
