Symptoms ever hit quickly or generally slow and gradual?

Everyone has a different experience with Sleep Apnea. In this community you will find that a lot of people have suffered with the symptoms for years before getting diagnosed. That was my experience, I've had the symptoms since a teenager but wasn't diagnosed until my late 30s. If left untreated, sleep apnea can lead to other worsening health problems. So it is possible if you're experiencing symptoms, they could have been there for a while, you just weren't aware the cause is sleep apnea. Have you spoken to your doctor as yet?
