This is just an excuse.

And not only will it cause you to delay giving up if you give in to it, but it is designed for a much more deeper reason:

To give you an excuse not to have to face the feelings you will experience when you give up.

So you keep running AWAY from these feelings, fearing they are too painful, too unpleasant and just too impossible to change. 

But are they ?

It is this lie that has kept you smoking for years - or - to be more accurate made you so FEARFUL that you kept on putting off the day when you would even try to quit this addiction.
