I don't have direct experience of this type of therapy so I can't really say for sure. I do know people who have tried it, and I've looked into it for PTSD. Since you asked for opinions, this is just my sense of it. I myself chose not to do it, and others that have wished they hadn't.

While they say it works, it's kinda too much. I mean you gotta just relive it. Not sure why reliving your trauma history is good for you. I guess you are facing it, but there are other ways, stuff that is slower and softer.

People with trauma are sensitive. I guess it's supposed to desensitized you? I don't want to be numb or forget it. I just want to not have it get in the way.

I like more supportive, gentle therapy. At least when doing trauma work, I want my T to be there like a witness so I'm not alone in what I had to go through and not talk about. I already relive things in my head; I don't want to do that in therapy. I want the opposite...to not feel like I'm forced into anything.

So that is just an opinion, based on my own experiences and others, and some reading around to find out about whether I wanted to try this or not. Depends on what you want, what the trauma was like, how old you were, how much it repeated, how severe the PTSD is, and of course how good the T is.

I have found that Judith Herman on trauma is the best cuz she describes what it is like to have all kinds of trauma and she maps out a path of recovery. It's about connection. Feeling connected to someone to feel the parts that were hurt and are disconnected. Starting really small and working slowly. Kinda the opposite of exposure.
