Started on 36mg and quickly dropped down to 24... I've slowly dropped lower and lower until i'm just touching 10/11mg and this is where i feel great. I find the more i vaped 18mg the quicker i got nicked out and i wanted to enjoy more vaping, so naturally i lowered my mg. I can now happily go all day on my 11mg and find my previous 20mg a bit too much. I'm happy that from a 40+ Marlboro reds a day, i'm now vaping a 'low/medium' content liquid.
