I made the switch from 18mg to 8mg last week and I can't tell any difference whatsoever. I really enjoy vaping, but beginning to wonder if I'm really getting a whole lot nicotine, or if it's just a mental thing. I don't find myself vaping any more or less with the 8mg juice, and I don't find myself grabbing for it first thing in the morning like I used to with analogs. I believe it will be easy when the time comes to go from 8mg to 4mg to 0mg and then quit altogether. I plan on doing it slowly and maybe going with another bottle of 8mg, then 2 4mg bottles and 1 last 0mg. That's the plan...I just hope I can follow through.
