I normally sleep basically sitting up due to acid reflux. I typically will lie down for maybe an hour or so before I get up for the day. I have had a couple episodes when lying down of gasping for air - I attributed it to being overweight. Over the weekend, I shared a hotel room with a couple of friends who told me I have sleep apnea. I've never noticed any issues when I'm sleeping propped up. I have not been to my doctor yet. Any thoughts? Thank you.
