This thing is very effective! After using 2-half months, it helps me eventually quit my 30 sticks-a-day 22-years habit. 1st-week usage it dropped my craving from 30 to 4/5 sticks. 2nd week to zero.
I am now totally nicotine-free, tobacco-free and breath naturally. But now over-supplied with excess unused e-cigarette products.....
