well, try chewing gums.
The first year of recovery dont quit just yet.
try to avoid going out with people who are smoking.eat fruits or chewing gum after eating dinner.avoid laces whose lots of people there are smoking.
well I think that you should take it slow and one day at a time because, you can use some form of a support group to help you, or meetings. But all in all you will power to want to quit has to be strong and your self determination has to be high.
