I know how you feel, if i'm not constantly on this forum, then I'm going back and forth between this site and other accessory and parts sites, or looking up well rated juices and mods, and of course spending too much money! I hope my addiction settles too before I go totally broke on this little habit....
I was on this thing constantly before and for months after I started vaping. Eventually my logons started to taper off as other interests became more paramount. And you'll find your purchases will likely do the same. After a while you'll accumlate enough "kit" to sustain your day to day needs and juice orders. But even considering your initial and splurge orders, you're going to save significant amounts of money. How much is entirely individual, depending on how much you smoked and how crazy you went ordering. But after a few months it starts to add up fast. You've just started your journey. Don't go too crazy, make sure bills get paid for, and enjoy.
