Good advice! One should always rule out the sleep apnea. In my husband’s case the intense snoring was a giveaway but in others it’s more subtle.
I didn’t snore much, but, before I would wake up, I’d actually dream I was running and could not catch my breath. I’d wake up with a pounding heart and completely out of breath. I finally saw the sleep doc and the tests showed pretty severe sleep apnea. At the time, I’d never even heard of it!
Oxygen deprivation during sleep is a serious problem and causes all sorts of problems including stroke and heart attack.
