I have had sleep apnia for 7 years and use a Bi-pap. When i went in for a sleep study i was having more than 100 incidents per hour. Sometimes i fall asleep at home now with out using my bi-pap and wake up with my heart racing. and i found out that this can lead to a heart attack. I now make myself put on my mask and get the sleep i need. I no longer fall asleep during the day anymore ether.
