Confused

Confused I have noticed something. Whenever I speak with tricks and avoidance of words, most of the time I'm fluent. Few months ago I started reading books about stuttering, and read all the stuff about not avoiding and that kind of things (you probably know). Lately, I tried to put that in practise, and the result is rubbishy. I block constantly, and can't put a good sentence together. I'm thinking myself, if this really is the cure, then how does it take to start working, cause it's suck to do that if that doesn't help at all. I would appreciate your thoughts on this. Thank you.
