11mg used to be too much for me, bite I mean, not the nic.
I currently hit 24mg all day long chasing a TH, and I just ordered some more 24mg, 36mg, and some 18mg to try to ween down on. (It hasn't worked yet.)
I really need to just hit the 36mg like once or twice, then set the thing down. This has worked the best for me.
If I am in the VAPE ALL DAY mood, I need lower mg.
