I have sleep apnea, in fact I have 2 separate types. The common or garden variety is called obstructive sleep apnea where the muscles that hold the tongue in place relax when you go to sleep and it drops back causing an obstruction in your throat and choking you, this where you stop breathing untill your brain realizes that your blood oxygen levels have dropped, wakes you up and you start breathing again. This can happen repeatedly (sometimes 100's of times) during the night, but you DON'T KNOW IT so you wake up tired.
When you have a sleep test you won't have a good nights sleep, I know but what the hell, you're not sleeping properly anyway .
If you have to have a cpap machine don't complain about the cost or the inconveniance, you are lucky to have been diagnosed BEFORE you went to sleep while driving a motor vehicle, your blood pressure will drop, you will be less prone to having a stroke or heart attack, you have probably added 10 years to your life, your quality of life in general will probably improve and you may even save your marriage ( which may or may not be a good thing
)
