Sleep apnea sufferers now have a new treatment option for restless nights: a pacemaker for sleep.
The last five years have been exhausting for Andrea Turner. Lights out for the 69-year-old meant sleeping for a couple of hours before being jolted awake in the middle of the night and lying there electrified.
"I was exhausted all the time, from the time I woke to the time I went to bed," says Turner. "It was like how can I make it through this day because I am so tired? I thought since I'm older so that's what it is."
