The Hulda Clark Flush recommends laying on your back. And Shellycat has had mucho trouble with her kidneys so she is the one you need to talk to. Wait for her to respond or post a message directly to her. She is on the West coast and I believe works during the day so if you're not in a hurry she is the best one to talk to. Mention the kidneys in your subject line and it will probably get her attention.
