I believe that irritation and anger may be a part of detox. I have seen it in children, have some myself in phases, also seen this a lot in homeopathy cases; phases of anger or grief that one has to go through on our way to health.
What has helped me through is spiritual books, meditations and other technics to calm my mind (your personality sounds a bit like mine, irritation because I am in a rush and five steps before others, always)
-also forgiving myself for having these thoughts, and others for being slow helps :)
I have also learned the hard way NOT to educate people unless they ask so. They will ask you, when they see what happens to you.
I have written a couple of posts about Iodine and IQ; yes it makes you smarter, and you will love the effect it has on your children ( well except for the anger phases and so on )
they will get less noisy, smarter, more emotionally stable.
Thats what happened to my two.
