I have been listening to the file that makes you forget a file, as well as another file that frankly I can't remember.(corny, but true). I also started listening to the files by cd. Up until a couple of nights ago, I have been using an mp3 player for them. It worked well, but I could do one file at a time. I tried burning the new relaxation file and some other files and a couple deepeners and I barely remember what was on it. I am surprised at how well it worked. I'm going to start doing that with other files.
