Was taking sleeping pills when I did my knee surgery two weeks ago. I stopped taking them since 3days now. I was feeling terrible in the morning but it helps.
Seriously, this "music" is just a strange collection of everyday noise put together. Some guy whispering with the sound of the ocean in the background, followed by the sound of church bells, birds, and a piano that sounds like it's being played by a 6 year old.
Tylenol PM is fairly mild. Really hard to get hooked on. I injured my back and had to used them for about 2 weeks. I strained the muscle in between the shoulder blades via hyper extension. I could only sleep on my tummy to avoid pain and I'm a back or side sleeper. It sucked.
If people are really having trouble sleeping I suggest running sometime during the day valarian root and camomile tea.
