What do you mean about blocks? The best thing that is really working for me is meeting people and talking a lot. I have been trying to minimize my stress with various activities (swimming/ diving/ praying/ breathing to control my heart rate/ talking to someone I love/ music)etc.. because I only stutter when I am stressed. I think it's important to surround yourself with good people, because most of the time, I even forget that I stutter. I was told that in The past I hadn't been able to speak one word without stuttering. But still, I stutter and it hurts me the fact that I can't fix it.
