Thanks for all the answers!
I think the therapists must put those letters after their names because they look good and rely on the fact that mere mortals will just assume they have some important meaning without checking. (glad I did now).
I'm sort of on the point of really not wanting to smoke any more but being scared of qutting (I know how pathetic that sounds). I've been at this point before and have given up, but obviously started again at some point.
I am dead against taking champix or other tablets for it. I've seen the way they work on some people and don't want to go there. Plus I'm already on some tablets that I really don't want to be on so I don't want to add to that.
Will keep thinking on it.
