To go on Rhythm: the chemicals, you may know this, adhere to parts of the brain that just love them (the un-conscious part) BUT the other elements in the smoke arent so good - obviously.
So, what you can do in regards to seeking some enlightenment (crazy word) on this aspect.
Basically, its like this.
The brain gets to like some of the chemicals in the nicotine: the deal is to break that.
Breaking it is obviously HARDER in practice that theory, as you know!
Its a bit like if you really love someone but they dont love you!
Sooner or later you've got to live with the fact you cannot have them.
