I used to sleep on the sofa a lot due to my husband's snoring. He would sleep on the sofa if he realized he was snoring before I did. We solved that ---- He has sleep apnea and is now sleeps with a breathing machine. AND ME.
When he took the test for sleep apnea he was sure he did NOT have it. I thought otherwise. They found that he would stop or nearly stop his breathing nearly every 30-45 seconds!
It was a life saver! Literally.
