Take on new activities that don't include smoking. Join an exercise group and work out regularly. Sign up for an evening class or a join a study group at your church. Go on more outings with your family or friends. Join quit-smoking programs if it helps.
Some people do better in groups, or with a set of instructions to follow.
That's fine, too. Remember, the aim is to quit smoking. It doesn't matter how you do it. Consider using nicotine gum and nicotine patches. Nicotine is the drug that is in tobacco.
