If you have a ton of liquid then you really didn't spend more than smoking, because if you stopped spending right now you'd probably still have enough to last you for the next six months (so calculate the next six months in as well).
Thanks for this response mate. That's my exact thinking. I literally have bottles on end because it's hard to suck down a 30mL bottle IMO. I maybe go through a vial of my kanger mini ProTank a day.
However, like I said, I would much rather pay more money to feel healthier than to continue down the path of stinkies.
