Tried nanostix last year after smoking for 21 years. Doesn't feel the urge to smoke cigarette unlike other vape. Used it for ~8 months then it broke down. Straight away quit smoking/vaping after that until now.

The trick is you need to control yourself when vaping, since you can technically just vape non stop per session either until you ran out of liquid/battery. Usually i just count 5-7 puffs/session, at most 10.

Another thing that helped me to quit when my nanostix broke down was I usually take a week long leave at the end of the year, it broke down near that period and since I'm not working, there's less tension/pressure leading to lesser urge to vape, plus even if I wanted to, there's no colleague that I can borrow their vape from.
