My Wife was only 4-5 butts a day, & none in 5yrs as well. 2 days after my 901 came in, I was ordering her one lol. She is running 18mg juice as I'm running 18mg so it's easy. *I do have 24mg for hard times. She was near the breaking point of grabbing a stink-cigg, life is stressful, & so she like the nic. A liltle nic isn't such a bad thing
