congrats on quitting phil! I blew through a lot of money early on to find what setup and juice flavors worked for me. Don't sweat it, it's still less than what you would have spent on cigs over time. And when you do find that winning combination you'll be satisfied and then only spend money on juice and coils.
I gave away my first few setups after upgrading, to friends that are still smokers, to try out vaping.
