When doing blocked breathing do you start wherever you are in your current breath or do you have to breathe in or out beforehand? And after doing it, is there a right or wrong way recover your normal breathing pattern? I tend to take a deep breath afterwards.

I've read the book and watched Doug William's video. In his video, he seems to indicate that doing just the mental reactions is better than trying to manually control your breathing. What's your take on that? 

All the things I've seen, especially in the video, showed examples of people showing no reaction to relevant questions, but what if you do show a reaction to one, even a large reaction, and they ask if you're using countermeasures and you show a large reaction to that, is the reaction to the control question going to cover it? Or does it raise red flags to that one relevant question having a reaction when you show little or no reaction to others?

Appreciate, as always, anyone's advice!

Thank you for your response, George. 

If that's the case, does controlling your breathing during relevant questions make a severe reaction less likely? 

Experiences that people have had here and in the book,there were double agents who passed. So they had to have some way of preventing a severe reaction to relevant questions. Was it just the breathing, do you think? Over time, I've psyched myself into thinking every little thing is going to get a false positive. Just afraid I'm going to be causing bad reactions all over the place.

Thank you, George. Much appreciated! The breathing thing he's been practicing did help him.
