Hi Houda! I recently quit (less than a month ago). I have quit several times in my life, but this time I really feel will be my last! I have always done cold turkey in the past (quitting without any aid) but this time I am using Chantix. I also set a quit date well into the future- I gave myself about six weeks to get used to the idea. I listened to audiobooks about quitting smoking (Allan Carr and others), as well as meditations before I quit. The Chantix has helped immensely with the craving and mentally I felt ready by the time I put out my last cigarette. Just remember you are not alone- I have even gone on reddit just to read about other experiences people have had and to remind myself why I'm quitting. Good luck- you are making a good decision!
