That book was highly recommended by the Trauma specialists I saw. It may be old, but there are a whole lot of ts out there who do not get that trauma is stored in the body. As least for me it has been true, and I have found SE to be helpful (which is what Waking the Tiger is about).

It begins with suggesting at least one exercise that can help you get back in your body. There might have been more than that, but I specifically remember the one.

I did have to quit reading it, though. He describes an animal hunt in a very triggering way for me. What I did was buy two copies, one for me and one for t1. T1 would read ahead and give me the green light to read certain sections or pages. And then we would discuss them. Since he had no experience with DID it was helpful to him as well.

Can you ground yourself if triggered? If not, hold off on the book and find other info about SE would be my suggestion.
