Oh yes. I'd say it was one of the easier file to work with. It wss the very first one I listened too, and it worked only after 3 tries. It's worked everytime since then.
I tried this file first time today and did not go when told but did uncontrollably wet when I stood up after the wakeup hmmmmmmm not sure what that means.
I have had some success with it, but since I have stopped listenening it has wore off. I found this file awesome. I am thinking about doing a pernament uncontrol of my bladder or so =]
