Someone must use 36 mg juices since so many vendors offer it. If so, do you vape less often than you would with a lower nic level? I started with 18 mg then went to 24. 24 mg usually works fine for me but today was one of those days that I was working and playing outdoors all day. Hard to keep the PV handy sometimes. If I could go up on the nic level and vape less I think that would be a good thing. What has been your experience?
