It does get easier as it progresses , It would sometimes knock me out early on and I would get very tired , but it is worth it. It's good to share experiences here about the things that happen. Quite recently in my EMDR I've felt like it's lanced a wound that's full of poison and I've felt weak and tired like you do after an operation , but its healing. My T said it was a good sign. I do think EMDR is very good for trauma.
