Thankfully，most people wake when the obstruction happens，but it can make you feel completely tired.OSA has also been linked to a lot of health problems including heart disease.
It's expensive to treat OSA.Doctors may require you to wear uncomfortable equipment，and may even include painful surgery(手术)．
