Thank you Teri! We have a fan, it doesn't hurt to try the sleeping on her side. She lives alone and is also afraid of falling asleep and suffocating. I read that you can sew a pocked into the back of your shirt and put a tennis ball in it to prevent from rolling onto your back. Heard of it?

She has a surgery approaching on the 12th (6 days) for her cancer (mandibulectomy + flap reconstruction) so if the sleep apnea continues to persist, we can formally pursue an ENT specialist, etc. I'm really surprised her ENT surgeon didn't say anything.

Everyone kept implying it was her nerves/anxiety keeping her up. But she can't take any sleep aids because of her breathing difficulty. Turns out it was sleep apnea + anxiety.
