I think once you spend about $200 to $300 on juice you will taper off and will be able to stop buying and control your urge to buy more easily. Right now i am almost a month in to vaping I bought the UU kit, blank and prefilled carto's, and juices from V4L. Also lots of juices from quite a few vendors as well. 3 weeks in and i have Dunhill, Mild Seven, Hilton, cowboy menthol, menthol, coffee, menthol ice, cappuccino, caramel, nuport, cool, smilin special menthol, and a few others in carto's and juice. And still have a few more flavors coming in soon. I am trying to find my fav vapes. So I think of it as a learning curve or just finding my favs and sticking to them.
