I'm trying to figure out how much e-liquid I will need for a month's supply. My funds are rather limited so I'm really trying to budget this thing out. I used to smoke 1 pack a day. It has been a little over a week since I started vaping. I've estimated that about 10ml of e-liquid will last four days. That equals about 35-40 ml of e-liquid per month. I'm so new at this, that I don't even know if my calculations are feasible. So, my question is, how much e-liquid do you use per month on average? I just want to get a general idea of how much everyone else vapes. Thanks in advance for your response.
