I must of posted on here 3 or 4 times a day for the past week with problems. Everyone has been so helpful. I re-read through all the posts and can't single out what the problem was but I'm half way though my 2nd tank full and my mini is fantastic !! Main things I think is using only the largest air hole occasionally going down one for a bit to rebuild the vaccum. Taking slow gently draws instead of sucking to hard and not vapeing in quick succession which I was doing as I wasn't getting a hit. Taking it all slow and I'm not craving at all now. I love my mini now. This forum is the best. Thank you all that helped my and kept patient with my constant different posts.
