In a message dated 97-08-18 12:16:04 EDT, you write: << You might have sleep apnea.(sp?) because of the lose of muscle control in the throat. >> My husband does not have PD, but does have sleep apnea. He needs a respirator called a c-pap on his face when he sleeps. Before he was diagnosed he continually stopped breathing during the night and never got a decent night's sleep, although he didn't know that's why he was always so tired. When you have it you never get into a deep sleep because you are always waking up enough to start breathing again, although you don't wake up completely. Sue, daughter of Rocky 74/15
