Thank you for the responses so far, and I hope more will respond. It only makes sense that our bodies suffer without proper oxygenation and good REM sleep. Sleep disorders (insomnia, sleep apnea, narcolepsy, and even restless leg syndrome) are disorders that are likewise often associated with PD. This is an interesting site you may want to visit that has a short "Sleep Test" and other information. http://www.sleepnet.com/ Peggy ---------------------------------------------------------------------- To sign-off Parkinsn send a message to: mailto:[log in to unmask] In the body of the message put: signoff parkinsn
