i have just started using a Sleep Apnea machine... Terrible thing... But i have lost sleep due to waking up lost in breath ./ not breathing. Mostly sleep apnea hits you around middle age . If you are tired during the day or dozing off it maybe worthwhile getting a sleep test done, around $900 at a sleep clinic. Machines start at about $1500 plus. If you dont do anything you could die of stroke etc.. I think this is how many die in their sleep. The mask is a nuisance. But i got used to wearing it.
