Thanks for your query.
Most important thing in quitting smoking
is motivation. so keep it high.
Heavy smokers have difficulty in quitting because of withdrawal symptoms
but you are light smoker. Withdrawal will be minimal or absent in your case. Major thing is craving in your case. Distract your self in sport, family and reading while quitting. It will help.
I hope this information has been both informative and helpful for you.
Wish you good health.
