Enjoy. You will notice changes - some subtle some dramatic. I never got the Sleep System because I seldom had sleep problems even at the worst times in my sitch.
Peace,
In addition to my above post, I just thought I'd mention that I used the sleep system last night and had two nightmares! Finally, at 4:00 am I turned it off! My head isn't used to hearing weird sounds, outside of the sirens of emergency vehicles, at night. Some of those CD sounds are creepy in the middle of the night. Maybe I should listen to it outside of sleep times to get my mind used to the various sounds. I once used another CD for sleep and had the same situation, weird noises that freaked me out while sleeping. I'llplay with it a bit and see how it goes.
