I'm just starting and have asked the same question. Thank you all for your replies.

I don't think the muscle armoring will ever go away for me. I've been dealing with it since I was eleven (in my neck and shoulders), and there may just always be where I hold stress and tension.

I also don't think my tendency toward hyper vigilance will ever go away. I want to learn how to use it in good way though. Noticing danger, when someone needs empathy, etc. But I just know that that means I'll always notice those little things that send me into a fear response.
