I rarely vape 3mg, but have 250+ ml of Element E Liquids, Pink Lemonade, in flasks...one of my all day vape faves, but I'm waiting until I buy nude nicotine armor base to add to it before I crack the seals. I'll be bumping it to 6mg, 9mg, 12mg.
Have around 2,500ml of various juices and the avg mg nic is 9mg. I only buy 6mg and 12mg anymore.
How high I vape in watts is purely determined by the e-liquid. I'll push it as high as I can as long as the flavor holds out. If the flavor disappears then I back it off.
