I have used EMDR for childhood trauma. Just a few times, but it really helped me. It was exhausting. I would go home and crash and sleep for hours afterwards. I sometimes felt such a weight lifted from me in the days after that I felt almost high. Then after a few days would come crashing down. But overall it was very valuable. I can now talk about really traumatic experiences from my past that before the EMDR would send me into terror.
