I have a VV mod - with DK-Tab, I'm somewhere in the 3.5v-4.0v range. After dropping from 18mg to 11mg nic, TH is either much better or I'm just used to it

Mornings and night, I'll vape @ lower voltage.
I've looked in to it, but I'm a bit apprehensive. For one, I have a 5 month old baby boy and don't want any accidental spills. Secondly, I'm not sure I really want to mix high levels of nic myself.
I do try mixing juices and have noticed some unflavored PG/VG juices for sale. I may just need to get some flavors and add them to juices that almost make the cut.
