Had it last Saturday - done by my yoga teacher who is changing career to become a PT and also cranosacrial therapist. Because of yoga, she already knows my body well.
I'm not sure anything happened, other than getting another form of therapy that, like massage, brings some level of awareness and connection between your brain (neurons) and your body (muscles and sensation). This, for me, is helpful.
I slept like a baby that night but not sure whether it's related.
I'll probably keep trying it. First, because I'm curious about it and second, as I can talk with her about meditation and other inside-focus brain exercises that help me calm down my nervous system.
