I vape the same, after getting where I need to be with 2 to 3 nice hits at 5 1/2 I'm good. I'm a flavor chaser, so I just dump out the abv cause it doesn't taste the same.
@360 welcome to the forum, the E-Nano is a great vaporizer. The sessions you're looking for is based on what number you set the dial and the size of your bowl by adjusting the screen in the stem.
