Sleep Apnea Treatment

I’m normally the kind of college student that gets 6 hours a night, and thats enough, and 7 is a great nights sleep. Within the last few nights I have been unable to wake myself up before 10:00 am. This included going to be around 11:00 pm. So I’m sleeping close to 11 Hours a night. My sleeping environment hasnt changed at all. My only concern is that it isnt even an issue of self discipline, as my alarm went off this morning I was unable to turn it off. I was messing around with button on top instead of the side(Have had the clock for over 4 years). When my cell phone vibrated and woke me up, I got up to turn off my alarm clock!

Any Expanations?
