This is a reply to All suggestions via a book by Nester. I have obstructive sleep apnea. Obstructive referred to the fact that there is growing opacity of the scar tissue up in the edge of the skull and nasal cartilahe. It has continued to grow and block my breathing. It's too close to the brain to be removed. If my mouth were to be kept shut while I was sleeping I would suffocate. Obstrutive means blocked. I appreciate your collective attempt to help.
