You have already taken the first step to quit smoking
and that is by taking a decision to do so. You can always speak to people who have got rid of the habit before.
The next thing that you can do is to reduce the number of cigarettes you smoke in a day gradually. Also getting yourself involved in some new and health activity also recommended that keeps you occupied. i also suggest you take counselling
at a center which will help you to keep your resolve and also provide you with techniques from reverting back to smoking.
