I'd originally went with a Volcano and a Sidesho - quit analogs immediately. After about 5 days I decided the Sidesho was the keeper and gave the Volcano kit to someone that wanted to give it a try. Right about that time one of my Sidesho batteries died, possibly from the PCC. In the midst of all that, I was trying to deal with the typical 3pc e-cig hassles, and got myself sick. So there I was with a bad battery, a possibly bad PCC, and no real way to charge the 1 good battery.
I went back to analogs for a 4 day stretch while I waited for my orders from V4L. Happy to report that I've been smoke-free since then - just over 1 week now. Now I'm going thru the process of finding my flavors, the ones that will fill in for the various times I used to reach for a smoke.
Like others have said, it's going to be a bit different for everyone. The main thing is finding what works for you. I see now that I was a bit too obsessed with the idea of 'breaking even' right away, and in doing so I overlooked the primary purpose and benefits of trying out this whole thing in the first place. It's definitely a process, so give yourself some time to adjust if needed.
