I haven't gone to 0 nic, but I did just buy my first bottle of 0 nic from Compenstine (Fadora Vapors). I'm vaping 24mg and it's way too much, I chain vape and get a bit nic sick sometimes.
My next order is going to be one bottle of high nic level and then mostly low level nic like 6 and a few 0 bottles.
