Having Trouble Sleeping? Sound machines help almost as much as medication

The September 2008 issue of Consumer Reports has an article on sleep, and their data shows that sound machines work almost as well as the latest prescription meds in helping you get to sleep with meds helping 75% of the time and sound machines helping 70% of the time, with far fewer side effects.

They recommend some dedicated sound machines, but your computer or phone will certainly do the job for free or cheap.
