<p>My dad snored horribly for years, finally was referred to a sleep clinic by his dr. He went to the clinic, and less than 2 hours into his overnight they woke him up. He had sleep apnea and his oxygen level had dropped into the 70’s - dangerous. They said it was putting him at prime risk for a heart attack. He has a small, portable CPAP machine now and he sleeps MUCH better. He also has better energy during the day and doesn’t fall asleep every time he sits down in front of the TV now!</p>
