Champix is the way....it's based on an antidepressant compound.
Originally the compound was given to alcoholics to stop alcohol addiction, they all reported the cravings for cigarettes reduced more than the alcohol.
Do not use nicarette etc...all you do is play the addiction game a different way.
Champix will always work but a lot of people are horrified at the price once the "free" PBS subsidised quota is used up....and probably why they fail after 3 months.
Just save the money on cigarettes over the initial 3 months and use it for more champix.
Definitely worked for at least 4 people that i can think of.
18 years this month without a cigarette, smoked for 22 years ..
