I had a hard time letting go of analogs. So, I started DIY about a week into vaping. I played with flavors until I found one that did it for me (let me let go of analogs). It is my own mix I call Java Jolt. Mixed it strong for the first few days (choked my hubby) , then my hubby extracted flavor from our home roasted beans and I made a smoother version of the same juice. I am loving this vape! And I am loving my new firefly!
