so I have been off analogs for two months now but the job I'm currently at gives me the opportunity to vape all day. I originally started out with a nautilus and would only vape 3ml or so a day of 18mg nic. Not too bad right? But now I got a Kanger Sub Mini and building my own coils. Due to the increased wattage on my ipv mini 2 I am sucking down 10ML a day if not 12. I lowered the nic to 6mg but my question is how much is too much?
