Well to me the health benefits outweigh breaking even.... I;ve already got easily a year supply of juice somewhere around 800ML all kinds of flavors I basically bought from three suppliers listed here who had killer deals and cost me between .26 to .30 per ML.
Though their deals are up they always have more, The ones I bought from are tastyvapor.us goodprophets.com and juicyliquid.com. I highly recommend Tastyvapor.us and goodprophets.com. Juicy liquid is great if you are a diy'er and have lots of supplies and are nice people

all of these three have been generous in giving extras or advice etc and Id recommend any of them for anybody's first time purchase etc.
getting back to health, I sleep better, feel better, even only being in my first month off analogs, I was smoking 2 packs a day, since getting a 510 I dropped all analogs altogether. If you are determined to get off analogs this is the best way IMHO to go.
I also noticed my pitbull babygirl best dog ever pepper is breathing better. She is always at my side and shes no longer sneezing all the time and making faces when smoke would come her way, she used to run when I would light up a smoke, now she doesn't even notice that im vaping and I can hear the difference in hers and my breathing so I know its much better for me.
