I think it has helped me through the first weeks of quitting along with the patch but I don't want to keep the habit of inhaling as it could lead back to smoking and I don't want to be addicted to the nicotine forever . I am weaning down I take 2 or 3 puffs in the morning then I hold off until just before I go to bed those two times a day seem to be the hardest for me. Occasionally when really stressed or on my work break I take a couple of puffs . I cannot find a disposable e-cigarette without nicotine and I don't want to invest in a more permanent type of vaping pipe or cigarette because I do not intend to stay on it . I am now 3 weeks quit today ! What really helps me the most with the hand to mouth and inhaling is a piece of a straw !
