I vape to not smoke. Combine to about 18 mg/ml, eat perhaps 4 – 5 mls a day. (Exhausting to know for certain, I at all times have 12 in rotation, all completely different flavors.) And about 65% PG, so I get the flavour and a little bit of TH from that. Do not want huge clouds, however I do get sufficient for vape rings.
I, too, have discovered that if I enormously cut back the nic I vape much more.
And, fairly proper on the (typically) smaller type issue, not needing to double up on the batteries helps.
