After 18 days goes my first spray running out, which I have not bought expensive at the pharmacy, and the first sprayer on, I'm smoke free after 33 years. After several attempts to quit smoking with patches, gum and Inhale the spray tube is just perfect. Although I smoked more than 25 cigarettes a day, to get with 8-10 sprays a day without me for more sprays or a cigarette. Often soothes the security of having the spray. In the beginning I had hiccups and burning in the throat, until I found the best and mildest method. I spray on the tongue tip and squeeze it equal to the palate without breathing through your mouth or swallow, so I wait 2-3 Minutes until I swallow the saliva and perhaps a sip of water chic afterwards. I wish everyone a life without tobacco!
